Greg,
Sounds like something got wrote to your Windows IE registry. You can try to run something like Nortons utilities registry fixer or System Suite Registry Fixer, or Windows Cleaner. If that doesnt get it, you may have to take it to a tech and have them run regedit on it and manually remove it for you. Please dont try this yourself! You can do irrepairable damage to your system if you dont know what your doing! Computer Geek, Frye's,or just about any certified tech should be able to help you get this out of your Explorer. Hope this helps,
RG
