AVG did same to me...simply refuse to update database...since I was unable to do it manually and i got pissed off, I just left bastard in red color and later it fixed on its own...what i did noticed is that every day scan start at 12:00, it always found some crap for deletion, even I wasnt surfing net at all or plug in any new device on computer...and I did notice that its reporting same stuff deleted previous day...point is..no matter i use computer or not, every scan, thing found something..and i think AVG will soon die on my computer..
