Something is downloading constantly on my son's PC and we can't figure out what it is. We tried closing all the applications and non-essential processes. Is there a way of finding out which program is doing it? Maybe set a program to catch a program?? Running Vista. PC mostly used for games. We are starting to suspect it might have something to do with DPCs, but we can't close that or do anything to stop it. We already ran this : http://www.majorgeeks.com/download.php?det=4566 Thanks for any help.
