No need to Install antivirus for Mac?

We no need to Install Anti Virus for Mac Book?
If NO ,How to scan data when Insert external HD?
If YES ,Do we have any good antivirus sw for mac?
Thanks in advance

For the full story, see my Mac Malware Guide.
Note that connecting an external hard drive is not a significant source of concern with the types of malware that are out there right now, unless you got the drive from a real bonehead who might have copied some malware installers onto it.  That's very unlikely.
Also, note that you'd be wise to turn off Java in your web browser and ensure that all Java updates are installed, due to the appearance of Flashback.G a few weeks ago.  See Flashback using Java vulnerabilities and Flashback infections becoming widespread.

    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.
    Actually, you cannot download Snow Leopard. You downloaded a Snow Leopard updater.

  • I'm trying to install Word for Mac, but it doesn't contain enough memory.  Any suggestions?, I'm trying to install Word for Mac on my 10.7.4, but there isn't enough memory.  Any suggestions?

    I need to install Word for Mac on my MacBook OS X Lion 10.7.4, but there are two problems:  1)  Microsoft sells only Office, not the individual programs, and 2) I don't have enough memory to do so (2 GB).  Any suggesions?  I'm currently using Pages, and it's worthless.  Should I install more memory and buy Office for Mac?  Is there another decent word processing program (preferably downloadable) that will convert my documents to Word?
    Thank you so much for your help and suggestions! 

    I woud buy a 4 GB RAM package and install it.  RAM is cheap these days and the additional RAM would also improve the performance of your other programs as well.  I have used MS Office for Mac as well as other free downloads, i.e., Open Office and Libre Office.  I have found that Open Office anf Libre Office perform just as well as MS Office and, because they are a free download also save you money.  Another advantage is that they also contain a database, which MS Office doesn't have.  They allow you to save files in MS format as well as standard text format.  I ave also used Pages and feel it is satisfactory, although a little clunky to use.  If you feel MS Office is the only program for you, then buy it and install it.  You really should consider adding the additional RAM as it will improve the performance of all your applications.

  • I am wondering if we need a antivirus for mac

    i am wondering if we need a antivirus for mac

    I suggest using third-party antivirus software in addition to the safeguards Apple provides.  I am not an expert on which packages are best. 
    Our company requires all employess to run virus detectors.  They do not specify which we need to run as long as we have one installed.  (They also don't require us to use a Mac but we all have chosen to have one.)  There are many good competing packages and so far as we know none of us have been infected without the antivirus software detecting it. 
    I use Sophos.  http://www.sophos.com/en-us/  It is free.  It has detected and disabled a few malware files on my Mac.

    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.

  • Avast Antivirus for mac or Eset Cyber Security 6

    Considering many threats nowadays on the Internet, including malware related to false pages, phishing pages, Java threats, I consider important to count on a security solution.
    There are 2 of them I personally consider the best ones on the moment: Avast Antivirus for Mac and Eset Cyber Security 6.
    Well, considering two important aspects - detection (higher scores it's better) and performance (lower system usage resources - like processors usage - it's better).
    What is your opinion about them considering your experience?
    Which one would you choose?
    Thanks in advance!

    "Avast" is perhaps the worst of the whole wretched lot of commercial "security" products for the Mac. It's worse than the imaginary "viruses" you're worried about. Not only does it fail to protect you, it destabilizes and slows down your computer, and it sometimes or always corrupts the network settings and the permissions of files in your home folder. Removing it may not repair all the damage, and neither will Disk Utility or even reinstalling OS X.
    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.
    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 anything reflexively.
    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 the free software  ClamXav— 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. 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.
    ClamXav 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
    ClamXav 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 ClamXav unless a network administrator requires you to run an anti-virus application.
    9. The greatest harm done by security software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but if they get a false sense of security from it, they may feel free to do things that expose them to higher risk. Nothing can lessen the need for safe computing practices.
    10. 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.

    Allan

    LibreOffice gives you most if not all the functionality of Microsoft's Office suite of products (Excel, Word and PowerPoint).
    ProjectLibre gives you most if not all the functionality of MS Project.
    Both run natively on OS X and are totally FREE.
    Lastly, if you need to access Windows computers from your Mac, Microsoft Remote Desktop is available for free from the App Store. It is a vast improvement over the Remote Desktop Connection that comes with the MS Office for Mac commercial product.

  • Norton AntiVirus for Mac.

    Greetings.
    I saw Norton AntiVirus for Mac in the market. Should we buy it and install it to secure our Mac?
    So far there is no virus can attack Mac OS right?
    Best regards.

    Norton is hopeless on windows, let alone on a mac. Don't bother. I run windows/mac on my macbook and have encountered several viruses all the time due to the large amount of things I download and not once has the virus crossed into my mac partition and I have rights to read/write to and from mac to NTFS and NTFS to mac partition.
    If you are that scared use Eset NOD32 through bootcamp in windows and do a complete scan on both partitions by using macdrive to access your mac partition.
