I installed avg free edition on a fairly old dell pc, xp os, for a friend about a week ago and when I left PC was running fine. Got a call today to say PC very slow, especially when sending emails. Can avg slow down a PC that bad and is it to encourage one to buy full version? I wont see them for a few days, whats the best free anti virus software these days and is it easy to uninstall AVG.
Or whats the best paid for option for non techie users?
