|as no one has posted on this one, I would suggest the following.|
return to a previous restore point that occured before the problem began.
do a file search for files that were created in the last week, and then search the suspicious names at.
if you come up with something that looks wierd, post back here and I will be happy to help you from there.
the other option would be to start in safe mode with networking and use trend micros house call, or another safe scanner from an online source (avast is a good one for windows 7 i hear)
