Hi. I was alerted to a malware infection the other night by AVG and Zone Alarm as well as by the fraudulent “scan your computer” pop ups and other IE pop ups (even though I use Firefox) and the fact that I couldn’t run Windows automatic updates.

Using Spybot and Malwarebytes Anit-malware (MBAM), I was able to reduce a big infection (including lots of Virtumonde/Vundo bugs and a few Smitfraud-C and MyWay.MyWebSearch bugs) and recover my access to Windows Updates. But two bugs remain, regenerating every time I reboot. They are:

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\MS JUAN (Malware.Trace)
and
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\MS TRACK SYSTEM (Trojan.Vundo)

When I quarantine/remove these with MBAM, the next scan shows zero infections until I reboot. Then the same two registry key infections show up, just to disappear again until reboot… I’m doing this all in safe mode, and my wireless internet radio is disabled. Also, I’ve tried scanning with Trojan Remove, AVG, VundoFix, and Spybot again and they all reveal nothing. I also uninstalled Java and manually removed remaining files (though I can see there are still files remaining in regedit that I’m afraid to mess with). And I’ve been repeatedly running RegSeeker and cleaning stuff out of some temp folders (though I’m not sure which ones matter and whether I should delete all files including desktop.ini files, etc.).

I keep reading about HijackThis, Super Antispyware, and ComboFix, and haven’t tried these yet. I’ve also read about using Avenger to remove certain targeted files. I don’t really understand which to choose and in what sequence or how to use them. I was hoping some kind soul with experience with this particular pattern (I’m seeing that it’s ubiquitous for folks right now) would walk me through what to do at this stage. Thanks in advance.

Hello sheara,

I see that you have an HJT log posted here: http://www.bleepingcomputer.com/forums/t/189312/hjt-log-for-vundo-infection-ms-juanms-track-system-regenerating-on-reboot/

We do not allow more than one topic for the same computer and the same issue as this causes confusion, and in this case may make the disinfection process more difficult.

This leaves you with a choice:

1) Have this thread reopened and the HiJack This log topic deleted

OR

2) Keep this thread closed and wait for assistance in the HiJack This log forum. Please note that that forum is VERY busy.

Please send a Private Message indicating your choice.

Assuming you wish assistance in the HiJack This forum, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
