I don't know of any free AV for the Mac. Virex is a reasonable choice as is the Symantec product. Both work well and will detect Windows virus's so that you do not infect the other side with your email attachments.
Bear in mind that neither of these products will be able to prevent the first OS X virus from getting through. An AV program is only as good as its last virus definitions update and, currently, there are no Mac OS X virus definitions in either company's definition file. OS X is inherently more secure than windows.
Go for either of the two products and run your firewall.
Hope this helps

Hello guys,
How secured is MAC from virus attack no one can guarantee. That is why Virex is created for MAC as MAC is gaining popularity and there maybe some virus writer try to prove their capabality. Soon or later MAC going to be a playground for them. I'm thinking of downloading virus protection software from internet.Is there any free software for MAC out there beside Virex which has to be purchased.
Do virus protection slow down my MAC in anyway? I experienced it on Windows PC as protection software running on the background, same goes to Microsoft antispyware. It is quite annoying when popup blocker windows pops out every time I switched page and my homepage always been redirect to some page even though I already quaranteen/delete them. This experienced really disturbing me and that explain why I thinking of taking proactive measures here before it strike me again on my Mac.
