    There is no need for anti-virus software for your Mac, but if you are absolutely looking for one I recommend ClamXav which is free and you can run only when you need to scan something as opposed to always running..

    There is a free and automatically-updated anti-malware system already installed in Snow Leopard and later. As there aren't any viruses for Mac, there's really no need to install an anti-virus. Stay off dodgy sites, don't pirate, and don't click on links embedded in emails and you'll be fine.

    If you are interested in more details, check HERE - also look at the other articles on this site for more information regarding malware.

    In addition to the advice already given, go into System Preferences -> Security & Privacy -> General; see attached pic - make sure that your setting for downloading apps is set to the level desired (mine is at the red arrow, i.e. apps that are available in the store or have been approved by Apple).

    Macs can get viruses. There's certainly fewer than our Windows counterparts but the risk is still there

    I use ClamavX and choose the downloads and Mail folder to scan in 'live mode' because it can detect Windows viruses/malware. I think it's always good to get rid of them before emailing a Windows user. Sophos AV for Mac is particularly good for this but, from my own experience, can occupy your CPU and memory more than ClamavX.

    Yes, far fewer. Zero for OS X to date.

    There's a lot of misinformation on the net.

    Charlie Miller (the legend) wrote a few nasty ones at Pwn2Own. My government department detected a few and reverse engineered them to make work more effectively. I wish I could upload the info but, as you can imagine, releasing confidential government data is a big no no.

    What I can say is the virus, although low risk, was quite funny to see in action. In short, it erased removable devices i.e. USB pen drives when inserted. However, it was detected simply because the virus would not work on a user who had no admin rights. A message would ask for the user's password. On an admin's account, the virus would run an AppleScript from /Library that would erase the pen drive with a exFAT partition.

    There are no Mac OS X viruses Charlie Miller or anybody else. Avoid Sophos like the black death and follow Nick's post.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    It disturbs me that a guy like SparkyMac, who works for the government, does not know what a virus is. Hint: not malware.

    Definition: a piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.

    How things work website: Computer viruses are small programs or scripts that can negatively affect the health of your computer. These malicious little programs can create files, move files, erase files, consume your computer's memory, and cause your computer not to function correctly.

    I know the different thank you very much. My computer science degree sorted that out many years ago.

    The virus had spreader itself by users accessing particular network drives. Like I said, I can't specifics but the whole story would have explained exactly how it worked and the affect it caused on the network, etc.
