    I have searched threads and I see various methods of removal, most just citing removal tools. I have tried Webroot Spy Sweeper, McAfee Scans both in normal and safe mode as well as Spybot SnD & Ad-Aware. I had a good amount of spyware that I killed off already with mostly with Spysweeper but everytime it detects Virtumode and it quarantines but always comes back. I'm bout 2 seconds from just formatting and re-imaging this thing. IE runs super slow and I suspect there is remnants of spyware still lurking about. I will post my HiJack this log and computer specs below. I'm trying one last thing, Symantec's Trojan.Vuno removal tool but I don't have high hopes. Here the info, see attached HT log... please provide some insight on this nasty.

    Welcome to Majorgeeks!


    As you likely already know is that malware is a massive pest these days and does its level best to hide itself in any number of places, So just a Hijackthis log will not show all the malware that can be on your PC, the full guide of our steps below has a few other logs that show alot of the malware on your PC and where they are located,


    Try this first Virtumonde aka Trojan Vundo Removal - some people also refer to this as WinFixer

    Then progress to the below

    Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

    I have done all as expected and had already tried the VundoFix. I have done the lengthy process as described and now have the log files for your review. Things seem to be running a bit better after a few finishing touches. If everything is looking good is it ok to remove all the applications? I have a registered version of spysweeper as well as mcafee running if needed. Also I'm seeing a log of error msgs at startup for missing dll's etc as it likely killed those as well. They were the ones that looked suspicious anyhow. I'm assuming there is a system file or folder where I can remove these startup or run commands for these dll's?

    I have maxed out the attachments at 3. I will post another reply with the mg tools zip file in a subsequent reply.

    Hi rplieth,
    Please don't remove the applications until we've had a chance to look at your logs. The Vundo variants generally like to keep a few files in hiding so it can get started back up again. It takes awhile to go through the logs, so thinks for being patient.

    Hi rplieth,

    8) Now run CCleaner at the default setting with the Windows tab as the top one.

    9) Please run C:\MGtools\GetLogs.bat and attach the fresh MGlogs.zip it generates along with the Avenger log.
