I'm helping someone fix their computer, and it's pretty screwed up. As I said in the title, it's pretty much incapacitated. I can't do anything on it whether it's running programs, accessing the internet, adding an external usb drive, etc. Also, when I try to do something or even when I do nothing, explorer.exe will spontaneously delete itself. Explorer.exe especially deletes itself again and again, when I go into safe mode. I went into msconfig and made the computer start up in diagnostic mode, but that hasn't helped either.
Every now and then though, I can do very limited stuff such as opening msconfig, regedit, windows explorer, the calculator, and stuff like that, but that's it.
Does anyone know of a particular virus that causes these symptoms? I figure my only chance to fix this thing or just to be able to load new stuff right now is with regedit. Are there any particular registry keys to look for and delete? Any help would be appreciated.
