I noticed there is always the occasional user looking for advice regarding anti virus software. To make the decision easier and provide some pretty good info along the way, av-comparatives.org had 16 AV/malware detection/removal programs going head to head in a comprehensive test. 10 malware samples were installed on a PC and the AV programs got a shot at them. Some did good, some did worse. Some are freeware, some have to be purchased. Here it goes: Article on ars technica: http://arstechnica.com/security/news/2009/10/av-comparatives-picks-six-malware-removal-winners.ars" Full (Removal) test at av-comparatives.org (PDF): http://www.av-comparatives.org/images/stories/test/removal/avc_removal_2009.pdf" [Broken] Full (Detection ) test at av-comparatives.org (PDF): http://www.av-comparatives.org/images/stories/test/ondret/avc_report23.pdf" [Broken] I know, everybody thinks that "their" program they are currently using is the "best", no matter what. I thought so, too, but after reading the tests I quickly dumped my "trusty" AV software and switched to another. I hope this helps some people.
