Problems with Explorer.exe after infection

Greetings to all, and an advance "Thanks" for any help that is posted.

Recently, the antivirus software that I have running on my machine (Toshiba Satellite, Win XP sp1) missed some malicious software that caused me some trouble. I followed the basic instructions found here and other places, and there is no longer any sign of the malware (that I can find with Ad-Aware, XoftSpy, AVG Free Edition, etc).

However, as the last of the infection went away, I lost my ability to use Windows Explorer. The machine would boot and "freeze" on a blank desktop (correct image, but no icons, taskbar, start button, etc.). I was able to access my harddrive through the task manager (to get to cmd.exe). The error message that I got was "Access denied", when using cmd.exe to call it. When booted in safe mode (which I am currently using), the machine has full functionality. The desktop icons are present, and explorer.exe works without issue. After a couple of other re-boots into normal mode, I am no longer able to access even the task manager.

I am not quite sure where to go from here, but a system restore is a LAST RESORT (too much of my dissertation is on this machine!). Below is the latest log from HijackThis.

If there is anyone out there who can help, please do!
Thanks,
Chris

Greetings again. I, for some reason or another, am now able to access the task manager under normal mode, though all of the same problems still persist. It looks like LOTS of stuff booted this time, but I do have some access. Again, all is well in safe mode.

A subsequent scan with AVG Free found that the Win32\Beavis.4350 virus had corrupted explorer.exe. What looks to be a clean copy of explorer.exe still lives on my system, though when I try to access it, the file cannot be found or I do not have permission...even tough I can see it. I am enclosing my latest HijackThis log to see if it provides any additional information.

Thanks again,
Chris

Moderators: Please consider this topic closed. Things continued to get worse and eventually required a clean reinstallation of XP.

Thank You,
Chris
