Here's A thought...

My Dad was looking at some knowledge base articles, and came across this one:

http://support.microsoft.com/Default.aspx?id=883256

He looked at a few of the suggestions and solutions listed on that page, and
on a couple others. He started looking at ActiveX controls, and tried to look
at the settings in start/run/gpedit.msc. This computer would not open it up,
saying it could not be found. Then he went to the registry keys listed in the
above KB article, and even though there was nothing different, something in
what he did changed something, because when he logged into another account,
Microsoft Anti-Spyware popped up a window asking for approval of a browser
modification, and all of a sudden problem's solved.

We haven't the slightest idea of how our looking at registry keys and trying
to open gpedit.msc, when he changed nothing, caused the browser to be
"modified" and thereby fixed.

Can you guys think of anything??!
