Hello all: Any help with the following would be appreciated - I've struggled with this for days and tried just about everything in the posts I've read. My system (running XP - Media Center Edition) was infected with (at least) prunnet.exe, gadcom.exe and csrssc.exe. I can't run Malwarebytes, Spybot S&D, Panda. I tried running Malwarebytes from an external drive with no success. My browser is re-directed away from all helpful sites. I've manually removed as many of the files as I can, but they reappear on reboot. Otherwise, programs run apparently normally, but very slowly, with the hard drive thrashing at all times. I don't want to let this beat me and re-format my drive. Help!
