Success! This was it:
Trojan.IrcBounce - Is your computer infected with a mIRC version 5.7 (as the Help/About/ menu will tell you) hiding as TASKMNGR.EXE (not to be confused with TASKMNG.EXE or TASKMAN.EXE)?
From the load of reports I recieved it seems we have a firm outbreak of this trojan. Trojan.IrcBounce is the detection for a collection of programs that a hacker can use to conceal intrusion and obtain administrator-level access to Microsoft Windows environments. After it is installed into your computer, it gives a remote attacker unobstructed access to your computer. I believe this trojan is used for the DALnet DDoS attacks. The trojan includes a copy of mIRC that hides as Taskmngr.exe actually being mIRC32.exe version 5.7. The Trojan uses this file to run all of its mIRC scripts, including Dll32.hlp, Dll32NT.hlp, Xvpll.hlp, Httpsearch.ini, and NT32.ini.
I removed the TASKMNGR.EXE file from the start up file using Spy Sweeper and then was able to remove all its bits with Norton AntiVirus 2006.
Thanks, Chris...
