Hello again,

Not too long ago I'd written to your team concerning a problem on my system. It's a tricky virus which seems difficult to kill off, it's process tree name is 3HFr37wd.exe. I had posted the hijackthis log and your team had me 'fix checked' on a particular item. It provided temporary relief (aka you guys nailed the problem file) however it seems to be respawning itself after being done away with. I'm curious to know if you guys can help me figure out the source that's causing this virus to regenerate itself. Last time I'd rebooted my system and posted the lengthy hijackthis log, (usually after reboot I close down all unnessesary process trees leaving a very small list behind), and from deductive reasoning I know one of these few process trees is the problem file regenerator -- so I'll just post the current running hijackthisd log (in other words: I'm going to run a hijackthis log now and post it, it's a small list that dosen't include nearly all the startup processes, one of which is an infected/malicious file)

The file that causes the problem that you guys had me fix was:
O2 - BHO: solution Class - {99C6D1BB-7555-474C-91DA-D8FB62A9CC75} - C:\WINDOWS\system32\t55RwbWD.dll

something from the following list seems to be respawning it after correction:

Lastly I understand it maybe impossible to tell from this list what's causing the problem to regenerate -- if there is any kind of software I can install to let me track programs' activities I'd be happy to give it a whirl.

Thanks,
Joe.
