Hard to believe Avast! scored so poorly. Like I've said, I've used the (free ed.)
Avast! for years. I do a complete boot scan 1-2 a month and a more thorough
scan with Avast! and various anti-malware apps every 3 months or so. I haven't had
a single virus or malware in probably 2 years. Avast! always picks up bad websites
as I try to connect to them and automatically cuts the connection.
As for payware AV, my only experience is with F-Secure and I hated it. It was
slow and it leaked like hell. And just the other day, Crécy had problems starting
the Combat Mission: Commonwealth Forces add-on. Turns out his (payware)Norton
was for some reason blocking the executable.
