I am getting pop-ups telling me I have a self-restoring Trojan virus. I can't get Internet Explorer to open but I can get on the net with FireFox. I ran a scan and it said I had two worms named C:\WINDOWS\system32\svnshost.exe(there is a sqiggly line above the n) and C:\WINDOWS\system32\svschost.exe can anybody tell me what these are and how to get rid of them.
