Do i need anti-virus and trojan etc. protection?

i am new to mac's and just wondering if i need some software or something for protection from the internet. i know on my old PC i needed all the protection i could get, but I don't know if leopard already has something to protect my computer? and if i need another program, what should i use?
Thanks

Mac OS X by design is probably more secure than Windows. There are no known viruses (and I mean this in the strict sense of the definition of virus) that affect OS X today.
That's not to say there will never be, and that's not to say that things like Trojan Horses (things that, if you run them, will cause damage to your system) don't exist. Because I could write a 1-line shell script that would delete your entire home folder, and I could write a little app and a few lines that, if you entered your password, could send an email to every user in your address book with a spam. If you the user okay that, I can do anything I want.
So what does this mean? It means you can use anti-virus or other "protective" stuff, or you can exercise a modicum of caution and do without. Personally, I'm in the latter category, as I think that type of software causes way more problems on the Mac than it solves... but I can't always recommend it for everyone. I know I get emails from my mom (who uses a Mac) about once every 4 months asking about some bizarre behavior she's seeing and whether it means she has a virus (she doesn't). For her, the peace of mind of having AV may be worth it (to me, if not to her )
Clear as mud?

  • 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

  • Do I need virgin PCguard anti virus and firewall switched on with Firefox

    Do I need to have Virgin media PCguard anti virus and firewall switched on when browsing with Firefox?

    The person who told you that you do not need another security program was wrong, Firefox is just a web browser.
    There are free anti-virus programs available if you do not want to renew Norton. Some examples are:
    * Microsoft Security Essentials - http://www.microsoft.com/security_essentials
    * Avast - http://www.avast.com/free-antivirus-download
    * Avira - http://www.avira.com/en/avira-free-antivirus

  • Do Apple products need anti virus software?

    Comcast says I need anti virus software for my email account.  Do I?

    Just for full disclosure, there are a handful of malware pieces out there. Also, "virus" is not the correction common definition. A virus is a particular type of unwanted, or damaging software. The more recent all encompassing term is malware, which is short for "malicious software".
    1. Viruses - Zero. Not a single virus of any kind has been found in the wild that affects the Mac OS.
    2. Worms - One long dead worm that reportedly infected less than 100 computers.
    3. Trojans - These are the most common (and there aren't a lot of them). They attempt to trick you installing them by pretending to be something else. They can't self replicate like a virus. Each infection requires the user's help to get it installed.
    4. Java attacks - These were the most recent. It was the first attack to successfully infect the Mac OS simply by visiting an infected web site. No user interaction was necessary. The easy fix was to turn Java off in your web browser. Leave JavaScript on. Despite the similar name, they have nothing to do with each other.
    Java, and the Mac OS have since been updated against these attacks, and the writers of these attacks apparently haven't been able to find a way around these patches. There have been no such attacks for over a year.
    Basically, the Mac needs no help. Those who do run AV software, or are required to (business office, school systems, etc.) are there to help catch the myriad of Windows malware that gets passed around. For the Mac in such situations, you're really just catching Windows malware that comes to you in the form of an email attachment so you don't unknowingly forward them to Windows users.

  • DO I need Anti-Virus for my Macbook Pro w/Retina Display?

    I am currently awaiting a MacBook Pro w/Retina Display and I am having an ongoing discussion with some work colleagues, since the Flashback Trojan appeared to infiltrate Mac's back in early 2012... DO I need Anti-Virus.. My argument is no, but everybody elses is yes!
    I would love to see some indepth feedback to send my PC lovers running!
    Thanks in advance.

    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.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. This feature is transparent to the user, but internally Apple calls it "XProtect." 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.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
    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 another 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 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.
    For more information about Gatekeeper, see this Apple Support article.
    4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. 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," "archive 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 users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software are likely to be infected.
    Software of any kind downloaded from a BitTorrent or from a Usenet newsgroup is unsafe.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
    5. Java on the network (not to be confused with JavaScript, to which it's not related) is a weak point in the security of any operating system. If a Java web plugin is not installed, don't install one unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
    Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
    6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, even supposing that they do any good at all. 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.
    7. 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. Windows malware attachments in email are almost always easy to recognize without computer assistance.
    8. The greatest danger posed by anti-virus software, in my opinion, is its effect on human behavior. When people install such software, which does little or nothing to protect them from emerging threats, they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
    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.

  • Mac doesn't need anti-virus software !!

    Is that true??
    http://www.youtube.com/watch?v=3wUmz8Vy9aM
    this guy say YES!
    and I agree with him !!
    what do you think??

    The question needs a better context. See:
    Do You Need Anti-Virus Protection for Your Mac?
    According to Rich Mogull's article, Should Mac Users Run Antivirus Software?,
    "The reality is that today the Mac platform is relatively safe. There are hundreds of thousands of viruses and other malicious software programs floating around for Windows, but less than 200 are known to target the Mac, and many of those are aimed at versions of the Mac OS prior to Mac OS X (and thus have no effect on a modern Mac).
    It's not that Mac OS X is inherently more secure against viruses than current versions of Windows (although it was clearly more secure than Windows prior to XP SP2); the numerous vulnerabilities reported and patched in recent years are just as exploitable as their Windows equivalents. But most security experts agree that malicious software these days is driven by financial incentives, and it's far more profitable to target the most dominant platform."
    Mr. Mogull is a computer security expert. I recommend reading the entire article as it is quite informative.
    For additional information on viruses, trojans, and spyware visit The XLab FAQs and read the FAQs on viruses and spyware.
    Read the FAQ from the XLabs. There are reasons for having anti-virus software on your computer in certain circumstances. If those circumstances don't apply to you, then you don't need anti-virus software +at this time+.

  • Does the Mac need anti-virus software?

    I have been told the Mac does not need anti-virus software. I have Kapersky on my Mac now and was told to take it off.  I was told Apple updates the protection software daily.  Any thoughts?

    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 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.

  • 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.

  • Bootcamp and anti-virus and is getting VMware or Parallel better?

    I am starting research that requires me to download File Warden in Windows, so I loaded Windows onto my Mac by using bootcamp. Is this partitioned hard drive that is now I guess a mini-PC in my Mac require its own anti-virus programs and such?
    Also, the research program that I will be using will analyze the data using Excel, so I guess I would also have to download Excel into Windows. However, if I just got VMware or Parallel, and ran the research program on my Mac, would that data be converted automatically to "Numbers" which I have on my computer? If I used VMware or Parallel would I still need anti-virus?
    Apologies if these questions are obvious, I'm new to this.

    Yes you need AV/anti-malware.

    You need to buy and install Office though you might want to see if Office 2011 for Mac will do for your needs.
    I would guess Numbers is not going to do more than import and may or may not be suitable.

  • 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.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    If you require anti-virus protection I recommend using ClamXav.

  • Do I need anti-virus software for my Mac Book Pro (purchased in Sept, 2011)?

    McAfee's website ...
    http://home.mcafee.com/Store/PackageDetail.aspx?pkgid=358&culture=en-us&affid=79 2&eid=covmcaggl89400000070427s&adid=8370783383&
    ... says I need anti-virus protection for my Mac (of course they'd like to sell it to me). Been a Windows man since Gates was just getting started. FINALLY switched over a few months ago. McAfee makes good points about getting this protection so I thought I'd sign in here and ask you guys (the experts:-)) what YOU think?? If I do need it, please recommend. I always heard that you don't need anti-virus protection for a Mac and was hoping that would be the case but I must admit it ... that sounds a little bit far-fetched/unreasonable. I don't mind doing it if it will add extra security and isn't too annoying as it has ALWAYS been on my Windows PCs through the years. Thanks, Dan

    No. You don't need AV software.
    What does McAfee sell? AV software so of course they are going to attempt to sell it to you. Their only interest is getting your money and nothing more then that. That web site is a total crock.

  • Stopping anti-virus and anti-malware scans from scanning diasabled user files?

    Using Windows Server 2008
    If I only disable old user profiles, does anti-virus and anti-malware still scan their profiles and all files contained there within? Is this something that will happen regardless of the old users status and during a "whole computer" scan?
    And if so, are computer resources still being used for these old profiles?
    Thanks!

    Hi LaEmperor,
    From my experience with different AV softwares, I can say that they continue scanning them as part of the filesystem, despite of being disabled.
    I am not sure about your question for the resources, but I´ll give two shots:
    1. From the system perspective: basically affects the space that the files from that profile are using. The leave also some information on the Registry hive, on .USERS\ but unless it is a large numbre, I will not be concerned.
    2. From the Antivirus perpective: Well, as usual, Disk I/O, RAM, CPU, etc...; so as much as disabled profiles, as much they will add to the usual amount of resource comsumption.
    Hope you find this informative.

  • Youtube video is not playing on my macbook pro laptop. I have norton anti virus and firewall installed on it.

    youtube video is not playing on my mac pro laptop. Just a blank screen shows up where the video should be playing. I have norton anti virus and firewall installed on the laptop. Could it have something to do with it?

    unless you have a partition for another operating system, such as Windows or Linux, most mac users would agree that any a/v software is completly unnecesary and will do more harm than good.  There is a free a/v in the appstore called "ClamXav.   Have you installed all software updates and also have you tried youtube using different browsers (chrome, safari, opera, etc)?

  • Does mac need anti-virus software?

    I've been hearing lots of different opinions and I just want a straightforward answer, do macs need anti-virus software, are they prone to threatening infection?

    Even if I download alot of files, perhaps from "uncertified users"?
    That depends. No anti-virus or anti-malware protection in the world can stop you from downloading and installing software that does whatever it is designed to do. If you want to install a program that wipes your hard disk, you can. If you want to install a program that steals your passwords, you can. There are many legitimate programs that do exactly that.
    Nothing can stop you from installing software on your Mac except you. That's what computers are designed for. The point is that you must always know what you're installing, why you're installing it, what you expect it to do, and how to get rid of it when you don't want it.
