If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

  • What is the best antivirus/malware protection software for a MacBook Pro?

    I bought my MacBook Pro in April of 2011 and it's been running fine ever since then. I do not keep too many files on my laptop and have everything backed up on a 4TB external hard drive. I have programs that keep my MacBook running smoothly and as fast as possible by clearing out unnecessary files. Recently, my MacBook has become slow and I now normally have to click on a button at least three times before the page loads or refresh the page. Sometimes I even have to force quit Safari and restart from the beginning just to load a web page. Programs will quit unexpectedly and downloading something takes ten times longer. I fear there may be something wrong with my MacBook and it might have a virus or something. What is the best antivirus/malware software to download? I'm leaning towards Norton Antivirus for Mac or Intego Mac Internet Security. Could someone please help me?

    1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
    If you find this comment too long or too technical, read only sections 5, 6, and 10.
    OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
    It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
    An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
    For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
    That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
    Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
    Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
    Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
    6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
    7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
    ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
    Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
    The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
    10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

  • What is the best spyware/virus protection program for the mac?

    I'm new to the whole virus protection thing, and I know there are very few viruses out there for the mac, but better safe then sorry right? Plus i'm mainly getting it for the spyware protection anyway. Does Leopard already have some protection for it? Or would it be better to buy a new program? Thanks.

    Normally the best defense against Virus and other scrap on the net is the User. Never agree to open something you are not sure about. Don't visit dangerous sites, and think twice before make a gesture.
    After almost 25 years on Mac, and with X system, the only use for a AntiVirus is you can pass Virus to PC user but that ot effect your Mac. If you use Parallels or Bootcmp (or booth) you need a AntiVirus and Anti what the need on the PC, because that take 20 minutes on PC to be infected.

  • What are the best affordable external drive options for my iMac ?

    Hello,
    I am a fairly recent newcomer to Macintosh as my primary personal computing platform. I have recently installed Adobe CS4 Design Premium Student Edition on a late 2006 20in iMac and have several important questions about external hard drives. First of all, everyone knows that using any personal computer (whether you its a Macintosh, or a PC running Windows and/or Linux) without an acceptable way to backup critical data is no different than driving in your car without your seat belt fastened. I need advice for a good external hard disk solution for backup and several other important computing tasks given the following realities
    1. Contrary to what I to originally thought, I do not have Firewire 800, but instead have access to dual firewire 400 ports in addition to USB 2.0. My concern over connection speed in regards to Adobe's recommendation to use RAID 0 arrays for scratch disks used by Photoshop CS4. Adobe also recommends that scratch disks for photoshop CS4 are assigned on a hard disk that is not your startup disk. Nontheless, Adobe has no objection to use your startup disk assuming it has plently of Free space (and mine does w/ 189.53 GB available)
    2. Do really need RAID 0 to achieve the performance I would need? I had prior Mac based training with Adobe Illustrator, Photoshop, and Indesign, in High school. I have not used this software in 4 years and am not only trying to refresh my skills but to learn the software. In other words I am still in the beginner stage With practice and patience, I will certainly learn the software and use it to the best of my creative energies. Given the situation if my work becomes complex enough over time how important is RAID 0 when I make purchase of an external hard disk? I known that the disk utility in Mac OS X allows the user to create a Raid array. This seems like the cheapest way to accomplish the job. However, the purchase of an external Hard Drive must be able to safely backup my system and also provide adequate performance.
    3. Speaking of backup, I am one of those users who is still stubbornly clinging to Mac OS X Tiger. However, updating to a new OS has been required ritual for my previous two PCs. That said given that Mac OS 10.6 Snow Leopard will be out in mere months, I do not see the wisdom now in upgrading to Leopard. After all as a higher education student, money is tight and see Snow Leopard as far more compelling and future-proof upgrade. Snow Leopard is getting better plumbing and will also include Microsoft Exchange Server support (possibly the biggest selling point). I also have interest in using Boot Camp in 10.6 (or 10.5) for running windows software (that are useful for my academics) and games (particularly Half-Life 2 and other Steam games that can run well within my Mac's fairly limited gaming capabilities. If I decide to use Boot Camp I have to partition my internal hard disk. This further complicates finding a very reasonable, affordable, and reliable external disk solution given everything that I have mentioned. Any help is highly appreciated.
    Thanks.

    I don't think you should worry about the RAID stuff. The only way you could create a RAID is by using external drives, or one those external enclosures with two drives inside. Any speed advantage of such a RAID would be mostly negated by the FireWire 400 connection.
    Use your internal drive space for speed critical functions. Use a FireWire 400 external drive for additional storage space, where speed is important but not critical, such as storing your existing media (including your things like your iTunes library files). Use a separate cheaper USB 2.0 external drive for your Time Machine (or whatever method) backup archive, where speed is not that important at all (some people even use a network connection for their Time Machine backup).
    You can get a FireWire 800 drive and use an adapter to connect to FireWire 400. The connection won't be any faster on your iMac, but you can use the drive later with a Mac that does have FireWire 800. There are drives that have FireWire 400 and 800, and USB 2.0.
    I like the drives sold by OWC
    http://www.macsales.com/
    I often buy the drive enclosure empty and find a good deal on the hard drive mechanism that I want. OWC sells most of their drives empty. My current Time Machine drive is actually one of these USB adapters
    http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/
    connected to a Western Digital 750GB SATA drive that I got for about $70. Found that deal through dealmac.com. Couldn't think of a cheaper way to add that large amount of backup space, and it works very well. The internal drive in my iMac is only 160GB, so most of my personal data is on an external FireWire 400 drive; both drives are backed up by Time Machine.

  • Do Macbook Pros need antivirus protection? if so, what is the best antivirus protection software?

         Do Macbook Pros need antivirus protection? if so, what is the best antivirus protection software?

    Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
    The most effective defense against malware is your own intelligence. All known Mac malware takes the form of trojans that can only operate if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
    Any website that prompts you to install software, such as a “codec” or “plug-in,” that comes from that same site, or an unknown site, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim.
    “Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
    Software with a corporate brand, such as Adobe Flash, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
    Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use ClamXav -- nothing else.

  • WHAT IS THE BEST ANTIVIRUS SOFTWARE FOR OSX YOSEMITE?

    WHAT IS THE BEST ANTIVIRUS SOFTWARE FOR OSX YOSEMITE?

    Here are some more thoughts to consider.
    There will always be threats to your information security associated with using any Internet - connected communications tool:
    You can mitigate those threats by following commonsense practices
    Delegating that responsibility to software is an ineffective defense
    Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
    OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
    A much better question is "how should I protect my Mac":
    Never install any product that claims to "clean up", "speed up",  "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
    Illegally obtained software is almost certain to contain malware.
    "Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
    If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
    Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
    Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
    Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
    Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
    Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iCloud, iTunes, or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
    Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
    Don’t install Java unless you are certain that you need it:
    Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
    Java can be disabled in System Preferences.
    Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
    Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
    Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
    The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver movies or other copyrighted content that is not normally "free".
    The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget it.
    Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
    The most serious threat to your data security is phishing. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
    OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
    Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
    If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
    Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
    Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
    Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

    What is the best antivirus software for a Macbook Pro...I recently received a message from Google that someone made an attempt to hack into my mail account and I needed to change my PW and verify myself as the user.  The message suggested that I run a virus scan to check for sny malware or other types of viruses.  I do not have any software for this and up until now have not had a problem....any help is appreciated.  I would like a simple but effective solution!

    It's worth noting that if your Gmail has been hacked, it would likely have nothing to do with your MacBook.  Hacking web based email is fairly common and it doesn't require any access to your machine whatsoever.  In the same way that you can simply go to the Gmail webpage through any browser, any hacker can use the same method.  It doesn't mean your machine has been compromised in any way (and it has likely not been).  I have never received an email from Google of this nature.  I have received notifications when someone has attempted to create an account with my name in which they basically say that there is no action required if you're the rightful owner.

Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
    An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
    For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
    That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
    Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
    Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
    Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
    6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
    7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
    ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
    Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
    The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
    10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

  • What's the best antivirus for mac???should i use one or not??

    what's the best antivirus for mac?? and also should i have one on my mac or not???

    Mac's use a Unix based operating system and other controls that make it hostile for viruses to thrive.
    However it's possible to carry Windows viruses to other Windows machines by a Mac, also there might be some corruption if your dealing with a lot of Windows files.
    So all you really need is a scanner to run when you need it, something like the free ClamXav is good.
    http://www.clamxav.com/
    Apple includes a anti-trojan/malicious program type anti-malware service built into all latest versions of OS X, it works and updates in the background.
    There has been many attempts at trying to "trojan" or trick Mac users into installing rogue software on web pages. If you see soemthing like this, best to just Force Quit the browser by clicking on the Finder and selecting Force Quit from the menu.
    A alternative browser like Firefox will offer more protection.
    If you run your typical day to day operations on a Mac in what's called "Standard User", with a separate Admin User account, you'll need to update your Apple Menu > Software Update and your Apple Menu > System Preferences > Security > toggle the "Automatically Update Safe Downloads List" check box on/off about once a week.
    Standard User provides more security restrictions, but is also designed not to intrude into those who are less capable use of the computer.
    Third party plugins for your browser like Flash and Silverlight (used on Netflix) require a once a week check for updates.
    Use a free service like the Mozilla browser check here:
    https://www.mozilla.com/en-US/plugincheck/
    Always back up your personal data and never install programs that your not 100% you trust the source of.
    If you have any questions or suspicions, simply ask the opinions of the more senior users here on this forum.
    Good advice is not to install any anti-virus like Norton that demands the operating system remain a consistent state. Apple changes things all the time, which breaks software like Norton or OS X itself when a Software Update occurs.
    There are two great free 3D games, simply search for: Nexiuz Classic and Cube 2 Sauerbraten.
    If this information helped you, please click "Helpful" or "Solved" thank you.
    Good Luck and enjoy your Mac.

  • What is the best way to protect my macbook pro? should I install mackeeper? Thank you :)

    what is the best way to protect my macbook pro? should I install mackeeper? Thank you

    MacKeeper is malware that charges a fee. Do not install it under any circumstances.
    Keep your software up-to-date with Software Update.
    Don't click on links in emails, retype the URLs to be sure you know where it is sending you.
    Don't download a "codec" or program to view content on a website from the same site -- standard viewers should come from the codec developer's site, not the content site.
    Don't fall for requests from your bank or PayPal to verify your information -- they don't do it that way.
    Download Flash only from:
    http://get.adobe.com/flashplayer/
    You did NOT win any contests you did not enter, and you are not the 10,000th vistitor to any site.

  • What's the best free anti-virus software to use?

    I'm looking for the best FREE anti-virus software for personal use. Suggestions? If you could give me the top 2-3 or those that clearly separate themselves from the pack, I'd greatly appreciate it. Thanks!

    Darien,
    Allan is right it's really not needed for MacOSX, but if you feel you need protection from viruses/malware download and install ClamXav. If you want real time scanning for files and downloads use the Clam Sentry feature. Open ClamXav, go to preferences activate clam sentry, when asked  what folder to watch just enter the / which will monitor your entire system. Hope this helps.
