I hope you realize that OS X is just as susceptible to viruses as Windows is. Viruses just don't target it because OS X's market share/penetration is so insignificant, it just isn't worth the time.Archangel768 said:I currently use the anti virus, Mac OS X Snow Leopard. It works brilliantly so far.
Another good anti virus is to not look at porn. That one is quite effective as well.
Finally, not downloading illegal things tends to help too.
On a serious note. People say Kaspersky works great. It's got a trial version.
Otherwise, I always used AVG free on windows.
Avast [http://www.avast.com/index] is great, and so is Avira [http://www.avira.com/].
For diagnosis/professional help, you'll want to download HijackThis [http://free.antivirus.com/hijackthis/].
Anti-viruses are really amusing because they act very much like viruses do, has anyone else noticed the irony in this?
