Yes, it's clear you have some nasty malware running. It looks like lots
of it goes undetected except the noted ramnit.a.

If I understood the sources I've read, this malware modifies executable
files with the effect of making them "droppers". It could be a new worm
has now adopted that function and you are seeing detections of the
modified files but not the program that's modifying them.

You were probably doomed from the get-go to have to flatten and rebuild.
Too many unknowns.

READ & RUN ME FIRST. Malware Removal Guide

Haven't yet found the beastie this procedure wouldn't clean w/o
reformatting a drive.

If I have time, I go though with it. if It's more expedient to wipe
the drive I just harvest data, and reinstall the OS. But I prefer the
'thrill of the hunt' so to speak.

Well, have you tried PC Butts' Remove-it software?

Whee Haw!!!

From Dave's first post...
"Does anybody have EXPERIENCE with Win32/RAMNIT.A ? I'm having a devil of a
time removing it. The only tool the detects it consistently is MS Security
Essentials, and MSSE keeps counting it and "disinfecting" it."

He didn't submit a sample somewhere, MSE scanned the system, detected it
(Win32/RAMNIT.A ), but MSE failed to full remove and clean the system of it. Dave also
indicated he tried Avast to no avail.

Multi-AV -

Having cast my eye through this post, I think I would have given PrevX a go :-)
...and having read
...I think (seeing as Sophos is armed against it), I'd try Sophos CLS from Bart PE cd :-)

You may want to try turning off "system restore" in
"system properties". Then reboot. You may also want to make
"system volume information" accessible to your malware scanner.
Then do a scan of that folder. The default setting is "read
only" and "hidden" so if it can be scanned the malware won't be
removed. The malware can reboot that last restore point over and
over and reinfecting your system over and over. A Linux based
scanner can be a way around the permissions but it's probably
better to do the scans within Windows.
