My Norton recently detected a "Trojan Horse" virus in my "C:\WINDOWS\Autoupd\" directory. The file is called "upd.exe". Norton couldn't disinfect it (as usual) so it's quarantined right now.
Now, I'd delete the whole folder and get it over with, but I have no idea what "C:\WINDOWS\Autoupd\upd.exe" does. And since it is in the "WINDOWS" directory, I'm thinking it might have some importance to the computer. So uh... can someone help me out?
