I have had trouble running Ad-aware for about two months. It always freezes at CLSID\73647561-0000-0010-8000-00aa00389b71. I have Windows 2000. I have uninstalled Ad-aware and reinstalled several times. This is the freeware software. I have no popup blocker installed at this time. I have done all this to try and solve another IE problem of when it tells me it's encountered a program and must close. Thanks for any assistance you can provide.
