PSW.Agent.ABKU - Stuck

[JGSmith]

My home computer appears to have acquired a PSW.Agent.ABKU infection.

A little background - the system has AVG anti-virus and Malwarebytes Anti-Malware. I've upgraded the Anti-Malware to the full version prior to this infection.

AVG is detecting the infection, but MBAM is not. I've gone through the process of validating each is running the most current definitions they could find through their update processes. The infection is in Winlogon, which to me points to a malicious DLL hooking into Winlogon, but using Process Explorer, I couldn't find any suspicious DLLs attached - everything was signed by Microsoft and those without proper descriptions did not appear malicious when checking their strings.

It looks like this may be a new permutation of the PSW.Agent, as the first post I've found through Google with the exact match was just posted in the last 24 hours - http://www.bleepingcomputer.com/forums/topic243465.html

Below is a HijackThis log run fresh this morning after doing another full system scan through both AVG and MBAM.

Hi,

Can you tell me what exact file AVG sees as infected?
