It appears that we have been hacked and files have been deposited that do NOT get detected as malware.
I'm running Trend Micro OfficeScan and everything comes up clean. I also scanned w/ Kaspersky and Symantec Endpoint Protection with "No Virus Found".

A process NTVDM (virtual DOS machine) keeps taking over the CPU. I can kill the process, but it always returns. If I leave the system for more than a few hours, there are multiple instances of NTVDM running that have to be killed.

The problem is on more than one system, one (1) running Windows Server 2003, sp2 and the others running Windows Server 2000, sp4. There is a process XXXXX.exe that I can only kill from Safe Mode, but it always comes back, with a new name. I found the file in the C:\WINNT\Temp folder. (see below HiJackThis log: G:\WINNT\Temp\QE7DD1.EXE, where G: is the system partition)

I've also found a suspicious "2.exe" file in C:\WINNT folder that I can delete, but it also returns before long.

I've searched and been unable to find any helpful info on this hack.
Running HiJackThis on the W2k3 server gives this result:
