Not for myself but can you help? My mates PC has contracted "I Worm/Netsky.T", whatever that is. In a moment of idiocy he removed his Nortons & ran AVG instead 'cos Nortons used up to much of his resources (huh?). Now AVG will quarantine the worm every time he boots but within minutes (not even time enough to get on the net)his PC freezes. What can he do to repair his PC? He can't get Nortons back on because of the "freezes". Thanks.
