Posted 22 July 2009 - 02:55 PM

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.

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

Hello and welcome to Bleeping Computer.

My name is Syler, I will be helping you to solve your Malware issues. Whilst I am helping you, I would
be grateful if you would note the following:
  • Please do not run other tools or scans unless I ask you to and follow all the steps I give you, in order.
  • Copy and paste all logs requested in you reply, Do not attach them unless asked too.
  • If you don't know or understand something, please don't hesitate to say or ask before you proceed with my instructions.
  • Please continue to work with me, until I tell you your machine appears to be clean. Absence of symptoms does not mean that everything is clear.
  • If I do not hear back from you within 5 days of my last post, then this topic will be closed.
