I work for an ISP Company.


Recently I have been getting emails at work warning people that there has been Macs infected with the Flashback Tojan connecting to some internal networks.  I have been also waned by my supervisor, manager and director to install an AntiVirus on my mac.


So which Anti Virus software is good.


In Canada my options are Norton, Kaspersky, Eset.

MacBook Pro, Mac OS X (10.7.3)

    Neither. Either will muck up your system.

    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 on the Internet 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?


    1. 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.
    2. 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.
    3. “Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
    4. 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 Migrate to a newer version of the Mac OS as soon as you can.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 the free software ClamXav — nothing else.

    Ok but compnay policy forces us to have Antivirus Program.


    So my options are:

    1) Install Antivirus Program on Mac os,

    2) Always run Windows with Antivirus (bootcamp) while at work,

    3) Leave my mac at home.

    Again, it has built-in protection. So everything you need to meet your company's requirements is built in.

    Because it's a company policy, ( Different Rules than the US )


    Here are your choices so your boss can see that you have a running anti virus in your MAC.


    ClamX AV is free and one of the good ones out there.


    Sophos is also free and loads on startup


    Avast is another free version and also loads on startup


    Stay away from:


    Norton - Useless on a MAC


    McAfee - same as Norton


    Although I feel the same as what the other's have told you, I too have to comply to the rules when it comes to installing anti virus software here in Canada.


    I've already told the companies I deal with the MAC OS X Lion is an Anti Virus software.


    In any event, install one of the following I mentioned and you'll be fine.

    Thank you for the advise.

    I would second the recommendations for ClamXav and Sophos.  However, keep in mind that neither will be 100% effective at protecting you from malware.  Read my Mac Malware Guide for the information you'll need to stay safe.




    Also, if you would prefer not to use third-party anti-virus, try telling your company that the Mac has built-in, always-on malware protection, called XProtect.  Unfortunately, XProtect is a bit low-profile, and many people don't know it's there.  This argument will probably get easier with Mountain Lion, in the form of the more prominently-featured Gatekeeper.
