One thing you can do after the HJT team help debug your system is switch to Trillian Instant Messenger
. It replaces ICQ , AOL , YIM , MSN & IRQ Chat clients . It takes very little resources compared to all the others running at once . And it does not advertise (no banners or popups).
If you are using XP also use MS AntiSpyware Beta1
. It WILL NOT work on ME or 98 .AVG Free Edition
is an excellent AntiVirus and the full verson is free . You will get tech support went you buy it .
