Moving post from Anti VIrus #1/AVG post with the intent of starting a new thread.
My current problem is very similar and it occured with Norton 360 Version 2.0 installed. Anti Vrius #1 hit me on Sunday. Malware removed it but also shutdown Norton. I tried reinstalling and it wouldn't run. I also had no internet connectivity. Uninstall Norton and I got my connectivity back. I've been dealing with a Norton rep all week. I've tried installing all Norton products, AVG and McAfee with no luck. I've also been exchanging emails with a Malware techie. The Norton rep was the one who informed me of the post on this forum regarding the tdisp file, which Norton asked me to send to their virus center. Looks like I need to try ComboFix. I'll post the results.
