One of the more popular antivirus software packages on the web is AVG antivirus. It is free and it doesn't use too much of the system's resources. I see over and over again most of the senior users on this site recommending it to other users (I also have been recommending it). I currently have it installed on all 3 of my computers. However, according to PCWorld's latest rundown on all the antivirus packages, AVG performed quite poorly on their tests: Of 10 antivirus packages, AVG ranked last. Source: http://www.pcworld.com/article/id,124475-page,1/article.html As antivirus software is something crucial to a smooth running system, the purpose of this thread is a discussion on what is good, and what is not. Should we really be suggesting AVG? Is PCWorld's testing faulty/misleading?
