I'm refering to the freeware version of AntiVir!
I like to have a program with a very good configuration...
Well, are you talking seriously?
AntiVir has so few configurations available... big update files, not automatic, lot of false positives... I use it like a backup (second, non-resident) scanner but avast is much, but much more configurable than AntiVir.
In this particulary case, you're touching the 'differences' between Home and Professional version, never a lack of configuration hability.
