A short while ago I somehow acquired a new toolbar tab that says
"TabsWin". I can't maximize it, or close it. Nothing happens when I click on it.

Where did this thing come from? If it's not a virus, is it Spyware? Whatever it
is, can someone tell me what it does, and more importantly, how I can get rid of
it ASAP? Thanks.

For what it's worth, I have Windows 98 on a Dell PC.
