Hello Bill -
I wanted to get back to you. As my last post said, I found PC-Doctor in my Registry and deleted it. I thought that would take care of it. Turns out, it did not and the PC-Doctor message reappeared. I then used your suggestion to use Autorun. Using that I found PC-Doctor located in other locations. PC-Doctor is also tied to uaclauncher.exe. It was surely an eye-opener the number of places PC-Doctor was located. I thought I had deleted the most obvious locations, but that was not the case.
Anyway, as of this date using Autorun, it appears I finally deleted PC-Doctor from all of its locations. Thanks again for your suggestions.
Jerry
