Kaspersky! One big thing: Kaspersky doesn't seem to have allegiance to Microsoft or any other companies. A full system scan actually shocked me by reporting all the problems with standard software from all the large software houses. Too, even though I only use the AntiVirus version (instead of the more-comprehensive Internet Security version), I have been warned about Internet sites far more often and feel I have much more browser protection than Symantec Internet Security would ever catch. I also think it runs faster than anything I've used. Friends that have used just about everything are quite happy with Kaspersky. No, I don't know if it's the best and I've certainly performed no testing but I am firmly in their corner. Thats my two cents. jimbo
