I had a similar issue a couple of months ago. I was instructed to go into safe mode and then find a restore point from a couple weeks prior. I don't know how far back your restore goes, but it worked pretty darn fast without having to worry about downloading new software.
You won't lose any files or documents you've added in that time period, just programs, which you can choose to re-load. However one of those may be the cause of the virus. Be careful doing that.
If you are unsure about safe mode or restore points, I'm sure someone here can walk you through it. I can't remember how I did it. It worked perfectly, though.

Last week The National Native American Museum celebrated its 25th anniversary. It was then relocated to Oklahoma to make room for the new Christopher Columbus Museum.
