When i run the full system scan my computer overheats and shuts down. I switch from Avast to AVG and now it looks like i should have kept Avast. I would like to keep AVG so do you have have any suggestions ?
thanks pat
p.s  I switch from Avast to AVG but now with this problem and the total lack of support it seems i made a mistake at least Avast has customer support for its free users.
