IMac anti virus software

Hi All,
I'm new to the iMac and I was wondering if I need to buy anti-virus software.
Some people tell me I do and others say you don't need it.
I do receive quite a few emails sent from Windows based computers if that information is helpful.
If I do need it, what would everyone recommend?
Many thanks,
Steve.

It self replicates and exposes your data, how many more boxes do you need to tick?
If you're happy exposing yourself to that risk then fairplay to you mate but to suggest to the O.P. that they should adopt such a poor computing practice is a bit rum to say the least.
Even Apple doesn't tout OSX as virus free anymore(for some time now), why would they abandon such a great selling point if it were the case?
It's funny that you should say that you've never encountered a mac virus, I must admit I personally have never caught one either -but then we both know what we're doing -right?. However, since I started visiting customers macs back when they were running System 6 and wdef was rampant it became painfully obvious that AV is required whatever platform you use. Infact even yesterday I was looking at a mac Word problem and the machine was literally riddled with 77 occurences of Word Macro virus, the customer was under the false impression that they were safe because they were using a mac and there are no "viruses" for macs... easy money- sign there, the invoice is in the post!

  • Is Anti virus software, such us Norton required on iMac?

    Just setting up new iMac. Should I install anti virus software such as Norton?

    It's not needed. Moreover, you mustn't install commercial antiviruses, because they slow down the computer and they don't do anything. OS X has got its own security systems as XProtect, so you don't need anything else and you can use your computer without worrying about it. See > http://www.thesafemac.com/mmg

  • Anti Virus Software for iMAC

    I have just taken delivery of my new iMAC and what Anti Virus Software would one recommend or NONE at all ? I see on reviews Intego Mac is highly rated

    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 actually been tested by Apple (unless it comes from the Mac App Store), 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. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
    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 find some other way to evade Apple's controls.         
    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. Beyond XProtect, Gatekeeper, and MRT, there’s no evidence of any benefit from other automated protection against malware. 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. How do you know whether a source 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 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.
    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. If you need to be able to detect Windows malware in your files, use the free softwareClamXav — 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.

  • Do imac's need anti-virus software?

    Hi there, I am new to imac, I recently just replaced my windows 7 laptop with the new imac 21.5 inch. I have heard some very different opinions on this topic and to be honest I dont know which way to go. Is it necessary to have anti virus software/internet security protection on my imac? Previously to purchasing my my imac I used Kaspersky Pure. My sister still uses Windows 7 and has Kasperky Pure also. So whats the right thing to do? Anti Virus or not? I just want to make sure I do the right thing.. and since Im new to imac I thought the best thing to do was to ask for some expect advice.
    Thanks

    Mostly there is no need. Apple provides malware protection updates automatically if something appears that represents a threat. In recent years there haven't been any serious concerns.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.

    If you require anti-virus protection I recommend using ClamXav.

  • Does my iMac need anti-virus software

    I've read recently that iMacs have been susceptable to viruses.  Does my iMac need anti-virus software?  And if so, d0es Apple recommend any one in particular?

    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 malware that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work 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 a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the 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 Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    Disable Java (not JavaScript) in your web browser(s). Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in Mac OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will probably never be fixed, because those older operating systems are no longer being maintained by Apple. Migrate to a newer version of the Mac OS as soon as you can.
    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.

  • Once and for all: Do I need anti-virus software for my Mac?

    I've always heard that you don't really need anti-virus or anti-spyware software for Macs - but I do wonder that there has to be viruses about that would affect Macs?
    I do alot of creative and professional work on my Mac. The data on it, means a **** of a lot to me, and I'd hate for my Mac to be infected with something horrible.
    Could anybody please tell me if I really do need anti-virus or anti-spyware software for my iMac? And if I do, which one do you recommend? (Ideally I would want it to be cheap and not hog lots of system resources)...
    Thank you!

    Hi
    I can only give you my personal experience on this one.
    The short answer is "no". I've been using macs for the past 4 years, my partner for many more. Neither I nor she have an anti virus program installed.
    We both use firewall on both the os x setup and via our router. I tend to install the security updates posted by apple after they are released and check the forums to be aware of any potential problems.
    A much better idea is to back up your important projects etc on a regular basis to dvd and external hard disk.
    I have one experience of anti-virus software on the mac:
    About 2.5 years ago i thought i had a virus - my diskspace was being eaten up at a very very fast rate - and i was worried. Found out that the os update from 10.3.2 to 10.3.5 had an incompatability issue with the mcafee shock game controller driver (obscure eh!)
    Anyway, after this experience and deleting the driver which i no longer needed, i decided to err on the side of caution and tried out both mcafee and norton. Both of which slowed down my system and norton especially caused problems when i was running logic pro etc. really really annoying.
    Once i'd got over my "insecure" stage and having spoken to other mac users i realised anti-virus software was causing many many more issues than resolving any - and besides since then i have still had no problems and have never come across any viruses on mac os x.
    It all depends on what makes you feel safer. Personally i wouldn't recommend ant-virus programs... i wonder if anyone has any positive experiences of anti-virus software on the mac?
    that's my 0.02 pence

  • What is Apple's position on Anti-virus software for the mac?

    I have started replacing my customers PCs with iMac's and Mac-Mini, and I have always operated on the assumption that anti-virus software is not necessary, but I fear that my opinion might need revisiting.  So I would pose the question again, does the community and/or Apple have an opinion on the need for Anti-Virus, Malware and all the other nasty inflictions.  If you, as a group or individually do recommend, what product would you recommend?  Thank You --- Bill Shaw - Kansas City, Mo.

  • Anti-Virus Software Needed @ Work in a Windows/Exchange 2003 Environment?

    I'm taking delivery of a new 24" iMac, and will be using it at work in a Windows/Exchange 2003 environment. I'll be using VMWare Fusion, and Win XP Pro 32 bit to run our business-critical applications. Also, until Office for Mac 2007 is released in January, I'll be using Office 2007 (including Outlook 2007) from the Windows partition. I'm the "pioneer" (the first) Mac user at our company and want to get this right. Regarding antivirus sofware (which I've never had to worry about on my home G5):
    1.) Do I need it at all?
    2.) Do I need to get it for the Windows partition? the OSX partition? both?
    3.) If I need anti-virus software for either or both, what is recommended, given my workstation/network setup? will the same product work for both OSX and XP? or do I need separate programs for each?
    Thanks!

    For the windows antivirus software I would avoid Norton. I've had problems with every version of it that I've used, both on my own pc and others. I've also had problems with Mcafee. Go with either ZoneAlarm Internet Security Suite, Kaspersky Antivirus, or AVG from Grisoft. AVG has caught things that norton doesn't. I use the free version in conjunction with ZoneAlarm on my XP machine, but they have business versions. Zonealarm's firewall works very well. The inbound/outbound program control is hard to beat. Their anti-spyware/adware solution leaves a little to be desired though. For the ultimate antivirus protection on a PC, you really need to run redundant programs.
    However for Mac, I can't recommend anything, since I'm not yet a mac user. Not yet.

  • Anti virus software - do i need it for my mac?

    Hi - with all the publicity in the news about the hacking of PC's and we only have 2 weeks to protect our computers from hackers - would you recommend that we purchase particular software for our iMac's to combat this forthcoming attack?  Any information gratefully received.  x

    with all the publicity in the news about the hacking of PC's and we only have 2 weeks to protect our computers from hackers
    You have to protect your computers from hackers all the time. The point is that you have to do that, and delegating that responsibility to some magical product that claims the ability to do it for you is an ineffective defense.
    There is no two week countdown to anything; there never has been.
    - would you recommend that we purchase particular software for our iMac's to combat this forthcoming attack? 
    Absolutely not. 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 "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
    Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
    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 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.
    Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
    Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore 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. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
    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 anti virus software to use with OS X 10.8?

    What is the best anti virus software to use with OS X 10.8?  Norton is slowing my iMac down and I'm constantly being bombarded by blocking messages for programs I don't recognize.
    Thanks

    Get rid of Norton a/k/a Symantec. It is one of the worst pieces of trash you can install on a Mac.
    You do not need any additional anti-virus software than is already designed into OS X to protect your Mac against malware. I assume you paid enough for your iMac and that's part of what you paid.
    If you use Windows, or are concerned about harboring viruses that target Windows, or care about friends who use Windows, then get ClamXav. It's in the App Store and it is free.
    Since friends don't let friends use Windows, I have no use for it.

  • Why No Anti Virus Software Required

    I am new to Mac and wonder why I hear and read that anti-virus software is not usually required ? This seems to be completely the opposite advice I hear for PC users.
    I use my iMac mainly for internet and e-mail, would readers advice I do actually install an anti-virus solution ?
    Note - There is a bit of debate on the BBC News website on this subject at the moment.
    Many thanks in advance.

    Some things, like clicking on a link and opening an email may not be safe; visiting a web site; an unpatched vulnerability in Flash, Java, or other plug-ins, those still exist.
    If you see a pop up that tells you to click on to scan, or alerts you that "your system....." it is malware. Ad servers can be infected. Google has had to try to clean their cache system.
    But virus in the traditional meanings of malware/spyware and rootkits or that AV traditional looks for...
    If you find that your email program doesn't filter junk or spot phishing exploits, you may, especially if you share files, or your ISP would hold you responsible for forwarding an email that while benign on OS X could affect the recipient's system.
    You didn't mention that the BBC thought it was UN-necessary:
    Eugene Kaspersky, co-founder and head of anti-virus research at Kaspersky, predicted a "significant rise" in Mac viruses back in April 2007. Has it happened? Not yet.... Symantec and McAfee both sell anti-virus software for Macs. So does anyone have any anti-virus software installed on their Macs? I don't on my machines. So am I smug and stupid or smug and wise?

    Now, do I own but not use AV? Yes. I want to have something in place, if it is needed. ClamXav, Intego both offer programs or suites. Safari is not my browser of choice by default, but it does log errors, and the iPhone might be the most likely portal for a worm or virus, someday.

    What is the best anti-virus software for my IMAC?

    If you are still using OS X 10.4.x "Tiger" please confirm.

    Use what Apple already provided.
    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.
    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 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.
    Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
    Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
    Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
    If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore 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. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
    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.
