If you haven't done so already, scan with Adaware and Spybot and let them fix what they find. You might also want to download HijackThis, make sure it is updated to the newest version which is 1.98.2, and scan and post the results of the log here. Don't attempt to fix anything yet, because most of what is in the log is needed. But if you have spyware, one of the experts will be able to point it out to you and help you get it fixed. :) Scanning with Adaware and Spybot is a good start though. Good luck!

Check for updates on both once you have them downloaded.
