Hey bro, I'm assuming you're on a network without a router, is this the case?? I've ran into this very thing on two other private networks I've worked on recently. The first network, I couldn't figure out how to get rid of it so I reinstalled the OS and it was clean until I plugged back into the network without a router. BAM reinstalled as soon as I plugged into the modem and was in the same boat as I started in. Put a router on, reinstalled and everything is running fine. If anyone is hooked to the Internet through DSL or Cable, I would HIGHLY recommend getting a router. One of my clients caught this virus that destroyed the partition on their hard drive and it started with those annoying popups.
