Galashi: Maybe you take me wrong buddy. I was just sharing my own experience trying to help others. That wasn't any kind of official procedure or guide. I keep the idea of sharing solutions, and not just complainings. Unfortunately i don't have any clue about Norton AV, so i can't help you (anyway, the folder exclusion was just an extra i made).
Willow: Hey, i use Avast from some 10+ years. IMHO it's a good one.
