best malware detector for mac
I'm interested in providing additional protection for my iMac by installing an application that will detect various forms of Malware aimed at the Mac OS X system.
Since Mac's are beginning to raise the interest of the hacker community, I would like to stay one step ahead of the "crowd".
I keep my system up to date with the latest updates/patches and I am very careful of the web-sites that I visit. But, one can never be too careful.
Are there any suggestions from the community?
iMac, Mac OS X (10.7.3), 21", i3@3.2 GHz, 16GB RAM
