AVG AntiVirus is a very capable program that helps you get rid of all the viruses and spyware on your Mac. The application brings you a simple and nicely-designed interface, so all Mac users, no matter their computer experience, can easily handle this antivirus utility. If you are running Mac OS X 10.6.x, a free upgrade is available from Mac OS X. Install all the available updates for your Mac OS X, and then download OS X.
I've had a Mac since 10.2, been using them since OS8 and only had one experience with a virus which didn't do anything to my Mac, but did infect a lot of my friends Window's PC's. I did a bit of research and found an anti-virus used by people who run OSX servers.

It's called ClamXav, is free to download and free to update. It sits in the background checking new files discreetly and has a component which you can launch and drag folders into to check. It also comes with a plug-in for CTRL-click contextual menu file scans. Seriously, Mac's are very secure but this is a no brainer. It's free, does everything other expensive solutions do and is a doddle to use.
• Answered by Samuel R • Jan 21, 2011 •. Taken from the Apple website (/macosx/security): 'no system can be 100 percent immune from every threat, antivirus software may offer additional protection'. So they aren't explicitly recommending it, but it is a feasible suggestion. Malware can affect a Mac, and it's possible to download something accidentally or to have a guest or another user download something harmful, so it might be wise to keep something on hand for that 'just in case' security. There are free options available, so no need to spend money.

Mac OS X, based on the ever secure BSD, is very resilient to such internet hazards. Many OS X viruses and the like will prompt for your username and password sporadically, without the user having done anything that would normally require it (Installing software, downloading software updates, etc).
A good rule of thumb is pay attention to WHAT you download, WHERE you download, and WHO you download from. Follow these three rules and you'll be fine. No extra software required! • Answered by Christopher S from Indianapolis • Jul 27, 2010 •.
