  1. I seem to have a Vundo trojan that refuses to leave! I have followed the 8 step removal instructions and whenever I re-run SuperAntiSpyware, it still seems to find some traces of it. I have also tried VundoFix.exe from Help is needed and appreciated.

    Run HJT Sacn only select and remove the below
    O2 - BHO: (no name) - {0183109D-E308-4A58-B409-9502D06D1DCC} - C:\WINDOWS\system32\tuvUNgHY.dll (file missing)

    Update then run SAS again and select and remove all.


    Download ComboFix

    NOTE: If you have had ComboFix more than a few days old delete and re-download.

    Get it here:
    Or here:

    Double click combofix.exe follow the prompts.

    When finished, it will open a log.
    Attach the log and a new HJT log in your next reply.

    Note: Do not click combofix's window while its running. That may cause it to stall

    There are still some remaining issues so still work to do!


    Download SD Fix to Desktop among other things Catchme to look for RootKits.

    On Desktop run SDdFix It will run (install) then close.

    Then reboot into Safe Mode

    As the computer starts up, tap the F8 key several times.

    On the Boot menu Choose Safe Mode.

    Click thu all the prompts to get to desktop.

    At Desktop
    My Computer C: drive. Double-click to open.

    Look for a folder called SD Fix. Double-click to enter SD Fix.

    Double-click to RunThis.bat. Type Y to begin.

    SD Fix does its job.

    When prompted hit the enter key to restart the computer

    Your computer will reboot.

    On normal restart the Fixtool will run again and complete the removal process then say Finished,
    Hit the Enter key to end the script and load your desktop icons.

    Once the desktop is up, the SDFix report will open on screen and also be saved to the SDFix folder as Report.txt.
    Attach the Report.txt file to your next post.

    Now Run ComboFix again and paste new log!

    This thing seems to have really done a number on my computer. I've followed your instructions to the T. Everything seems to be fine, but when I ran SDFix, I saw one of those blue screen fatal errors. I wasn't at my desk at the time so I only caught a glimpse of it. Something about "... serious error... beginning to dump from physical memory..." then it disappeared, Windows loaded as normal and SDFix kept on going. Hope that was all "normal".

    Attached are the logs. Thanks for all your help, Mike!

    LOL it wasn't the program!

    You were loaded with Malware!

    Run SDFix again to confirm it runs normally now.

    Post its log and a new HJT log!

    Yes, beware of blue screens. Ran SDFix again and paid close attention this time - same thing. It happens after the computer reboots after Safe Mode. SDFix starts running again, then I get the creepy blue screen:

    "A problem has been detected and Windows has been shut down to prevent damage to your computer.

    A process or thread crucial to your system operation has unexpectedly exited or been terminated."

    etc. etc.

    "Beginning dump of physical memory"

    Then blue screen disappears, computer reboots (again), and SDFix keep on going till it gives me my log.

    Ugh. Help..

    OK lets look a little deeper.

    Download Trojan Remover
    This is a fully working 30 day trial.

    D/L NOD32 stand alone cleaner:

    Download HostMan
    Unzip, install, allow it to turn off DNS Cache. Click update select all 3 host files. Have it replace not merge your host file


    Boot to Safe Mode.

    First run Trojan Remover attach log when back in normal.

    Then NOD32 attach log when back in normal.

    Reboot to Normal delete the SDFix install program then delete the SDFix folder that contains the Runthis.bat.

    Then re download and install SDFix and run it again watch to see if issue is gone.

    Mike, when I run the Trojan Remover, I get a window saying:

    "HOSTS file - malicious entries!"

    It asks if I "would like Trojan Remover to reset the HOSTS file to the default provided by Microsoft, with no re-directed entries [recommended]?"

    Should I reset the HOSTS File?

    I've run HostMan already

    Yes but after the trojan scan is finished update Hostman to put any it needs back.

    These are likey fasle positives.

    Mike, that seems to have done the trick! When I ran SDFix this time round, it went straight through with no problems. I can't seem to find the Nod32 log, even though I set it up create a log and also to scan and list all files (it ended up running for over a day). Nod32 did find a few things though - I made sure to delete all those. But there are another two files it found where it would not give me the option to delete (only to Leave). Those were found on the system restore files. How do I go about deleting those (or is that even necessary)?

    My PC seems to be behaving normally again. Should I be uninstalling any of the programs I've used or are some of them worth keeping?

    Thanks again Mike! You've been a great help!

    Do the below to get rid of the special programs ComboFix and SDFix. Uninstall the Trojan Scanner after 30 days if you don't want to purchase it.

    To clear the files in System restore rt click My Computer and click properties. Turn off SR then turn it back on. You will be directed to do a new clean SR point in the steps below!

    Thread closing-------------------------------------------------------------------------------------------------------------------------------------------

    Some of these tools update so often they require downloading again later if needed. But keep and run MBAM and SAS to maintain.

    Remove ComboFix
    combofix /u
    Hit enter or click OK.

    Please download OTCleanIt

    Save to desktop.

    This will remove all the tools we used to clean your computer.

    Double-click OTCleanIt.exe. Click CleanUp. Yes to the "Begin cleanup Process?"

    Approve all if prompted by Firewall. Approve Widows Defender or other guards or security programs while OTCleanIt attempting access to the Internet to allow all.

    If prompted to Reboot click, Yes.
    OTCleanit will delete itself when finished, If not delete it by yourself.

    Run CCleaner again twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

    Run ATF-Cleaner Temp and Registry, repeatedly until no more found.

    Fantastic cleaner.
    The issues can and are likely found is in System Restore so do the below

    Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

    Then Start-Programs-Accessories-System Tools-Disk Cleanup
    Click OK to accept C:
    Select all Boxes
    Then click More Options
    Here click System Restore and OK to "Are you sure" and the OK to Run.

    As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

    It clears what is known as Shadow copies which are used by specialized back up programs.

    This is if you have the Volume Shadow Copy running which is the default.

    Every two weeks or so, run MBAM and SAS until clean.

    They take a while, so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be scheduled not to interfere with computer time.

    If they find something they can not clean, then get back to us.

    Additionally run CCleaner. ATF-Cleaner and KCleaner.
    I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

    It was designed to be used with and to co-exist with other Virus scanners.

    Additionally it uses a totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity.

    It's like looking at it with 2 sets of eyes and from a different angle.

    It works like some Firewalls do to learn what is good/bad.

    After install it will ask you about everything that could be a security issue. For example the first time you run IE or FireFox it will prompt you. You would answer to approve and remember the setting. From then on no more prompts about IE or FireFox unless the exe changes like in an update.

    As it queries you about the prompt to help you determine to approve or not you can google it with one click.
    Look at

    Run SpyBot ocassionally and use the Immunize function.

    I highly reccomend Hostman: Hostman

    Download install run and allow it to disable DNS Client and select all Host files and then Update and install all host files.

    A Disk Scan (chkdsk) and Defrag are in order.
