OK, more evidence I'm kind of dense...
Started a full scan this am of Windows Defender, then had to leave for a job. My wife left the program open so I was able to see the results.
Nothing looked aims, but I noticed "review results of scan, so I click on it and find that "Windupdates.MediaGateway" was flagged as a high risk (or annoyance potential) so I clicked remove and it was removed successfully.
I hope this rids me of the ad ware menace!
Wish we could send the people who write these programs to Abu Grabe...
