So I contracted a virus earlier via RegCleanPro/Sys Tweak something-or-other. I think I managed to purge it all, but something remains. The start button that was down at the bottom left of my screen is now at the top left, and it blinks. When I try to click on it, either left or right, it goes away so I can't do much with it. I can't even drag it down to where it once was. Any suggestions?
