explorer.exe

yes this definitely sounds like a virus. Explorer.exe is one of the most well known processes because it's vital. For you, it appears it has either been replaced by a virus or a virus has been injected into it... which is pretty hard to get rid of. Try googling: ad aware and get the free edition. Ad aware does good scans.

explorer.exe can't be replaced by a virus and most virii disguise themselves and some of the main processes eg. explorer.exe and svchost.exe mostly svchost.exe as you'll see many of them on the process tab
