Here are a few of the things that are happening:
* When I click on a tab, they just rapidly cycle, though if I move the cursor down to the page, I stay in that tab.
* The volume in VLC Player turns itself up to 200% and when I try to turn it down, it just goes back up again.
*The speaker volume, on the other hand, insists on returning to 0% no matter what I do.
* In, say, Windows Security Center, when I try to scroll down, the cursor automatically returns to the top of the page.
There's more, but you get the idea.
I ran a full scan, and no
threats were found. I'll probably do an offline scan next, even though I have little hope that it will help. A system restore is on the horizon.
Computers are great till this kind of thing happens. Then they are hateful demons intent on driving a person mad.
