Having been recommended Avast Free by a friend, I got rid of AVG and downloaded Avast Free 4.8 yesterday (14 Aug 09). On opening up today two hours ago, my computer has a delay of between 5 and 10 seconds on any action I take including typing. Grateful to know why and what I can do to resolve the problem. Also how do I know when Avast is scanning and finally how do I adjust the scan settings to take out, for example, scanning of outgoing e-mails. Grateful for some assistance as a bit of a newcomer!
