AVG 6.0 should surely be at the top of everyones list as far as antivirus products are concerned. AVG uses so little resources, approximately 1700 KB, that none of the other well known products can compete in that area. There are issues that others have brought up as far as protection AVG provides mainly concerning script files. That has been improved from version 5.0. I dont think this is a concern. However, if it is, simply download a program called Script Sentry. Again, I dont forsee this being an issue but for the security guru and over paranoid freaks. AVG does not support very many email clients. Everyone who uses AVG should make the switch from whatever they currently use to Eudora; instead of Outlook, if they want to use this feature of AVG 6.0. All other antivirus products cannot compare to AVG. Just so you doing think I work for Grisoft...I am a college student in the US. I have also beta tested every major antivirus application, 11 in all, and have personally found AVG to be the best. AVG is what I chose to protect my system.
