make sure both your AV and Adaware definitions are all up to date.
download spybot search and destroy, it cleans up what adaware leaves behind and its free at
www.download.com
use all the scanners and if you're still having problems, hit control-alt-del and look over the programs that are running on your computer. run a google search on the ones that seem unfamiliar
programs like tskmgr, svchost, and system idle process are all common windows programs. so if you're unsure of anything research it. if you find out you have something viri or spyware related, try to manually shut it down, and remove it. if you cant get rid of it manually, go into safe mode and delete it.
to bring up a list of what programs start up on your machine, go to start---run----and then either 'msconfig' or 'services.msc'
also make sure you have all the updates from windowsupdate.com
make sure you have the latest drivers for your hardware as well.
and if all that still does not work, unplug any newly added hardware and see if this resolves your problem.
if not, reinstall windows
hope this helps
