I was recently infected with Virtumonde. I thought I had gotten rid of it with the rkill/MBAM combo, but it - and other trojans - are occasionally sneaking on. At the moment, AVG Free, MBAM and S-S&D find nothing; sometime in the next few days that will likely change, if previous patterns hold true.

I'm not visiting any websites that would dump anything on to my system, nor downloading anything suspicious.

Before, when I ran rkill, it was in safe mode and Chrome was not running. I tried running it just now, when Chrome was active, and it killed all of the active Chrome processes (I believe there's one ofr each extension.) If there's not one for each extension? Well, there's part of the problem.

I tried uninstalling Chrome, and then reinstalling it. The extensions and bookmarks remained, so the uninstall was clearly a partial one. A little research suggests that Chrome leaves behind a few configuration files and registry keys.

My Chrome is 4.0.249.89 (38071)

My main question is: does rkill always identify this version of Chrome as a malware process? If not, and Chrome is infected in a way that isn't being found by the various programs I'm using, then how can I scrub Chrome completely out of my system?

I have advised Grinler who created Rkill.

A log file should have been created and saved to the root directory, C:\rkill.log
Copy and paste the contents of rkill.log in your next reply.

Yup...rkill kills exe's running from a user profile. Programs should not be running from a userprofile as they are meant to hold data, preferences, settings, and configuration files.

For some reason, google continues to have their programs execute from within a userprofile.

Is there any way I can make sure that Chrome isn't infected? This stuff is creeping back on somehow. I'm all for alternatives to the programs I'm using, as well. If it helps, I'm getting hit with variations of Virtumonde.prx and Virtumonde.sdn.

Thanks for all of your patience on this.

Your concerned its infected because Rkill kills it? If so, then you should not be concerned. You can always double-check by scnaning it at http://www.virustotal.com/

Ah, great tool. I was more concerned because something is continuing to download this stuff to my computer, and the browser exe seemed like a reasonable suspect. Is there another program I should be using outside of AVG Free, MBAM and S&D to ferret this out?

Have you ran Secunia Software Inspector?

It could be an outdated app like adobe reader getting exploited.
