I just download the free version of Malware. I ran it in safe mode and it found and quarantined several trojans in the registry. Voila, I was then able to load Norton in safe mode and it found some others. When I restarted in normal mode, everything was working correctly. All progams now load the correct startup page with no error. Hopefully, I won't have to format and reinstall the hard drive. Thanks for all your help.
