For the last few days, 5 to be exact, I have received a popup window when I
have turned on my computer. The message in the popup says "This OS is not
supported." I got a virus via MSN about a week ago, but successfully removed
it with the help of a friend (we used programs such as Hijackthis, Combofix,
OTMoveit, and MSNfix). I also uninstalled and reinstalled Windows Live
Messenger twice, just be on the safe side.

But, ever since the virus was removed, I have had this popup turn up
instead. And it is really starting to bug me big time cos the computer works
just fine and the same friend has help me perform scans of the hard drives,
but we cant seem to find anything that would cause this particular problem.

Anyone who could give me some tips on how to proceed?
