Hi Bobbye,
Appreciate all the help. Regarding your comments, I was a bit surprised to hear the recommendation to remove McAfee, particularly because I've always been pretty happy with it. Seems to block most virus issues I've ever had.
I downloaded the latest version of HijackThis and ran the program as you recommended. The 020 entry for the Windows Geninue Notification did not pop back up unfortunately.
However, here are my scan resutls from HijackThis. Hopefully, you will be able to get to the bottom of this!
