There are two new Virus / Malware software packages available or soon to be available. The first one is Sophos, which is free and available now. http://www.sophos.com/products/free-tools/free-mac-anti-virus/download/ The other one costs $40 and I doubt it's worth the money because Sophos seems pretty good and no performance hit that I can see.
