Trojan Vundo removal problems

    Hi,

    Recently I've had AVG detect the vundo trojan multiple times and I ran the read and run me first programs. However, I realized that my installations are most likely not up-to-date, but I thought it best to post my logs before getting the newer versions and re-running them. Whenever I try to run firefox the program immediately quits out, and after a little bit of searching on mozilla I came up with the file vdhgml.dll causing that particular problem. I've looked through the other threads and seem to be at a loss for fixing this problem.

    Note: I initially ran SAS after AVG detected the trojan, and then once again after the firefox problem started. I removed some adware from add/remove programs which resulted in different logs, so I just attached them both.

    Thank you very much in advance.

    You did not follow the instructions in the READ & RUN ME and as a result you are WAY out of date with your versions of SUPERAntiSpyware, Malwarebytes and also MGtools.

    • Please uninstall your current version (this is necessary).
    • Then download this SUPERAntiSpyware
    • Install this new version. It may tell you that you need to reboot to complete the installation. You must reboot at this time.
    • After the reboot, run SUPERAntiSpyware and immediately click the Check for Updates button to get more updates for the database.
    • Now run a new full scan of your system. And attach this new log.
    Now run Malwarebytes, and make sure that you first select the Update tab and update it to the current version and database. Then run a new scan with it too. Attach the new log.

    Now goto this link Using MGtools and download the new version of MGtools.exe from the black bold print link in the first sentence. Overwrite your previous MGtools.exe file with this one.

    Run MGtools.exe then attach the below log:
    • C:\MGlogs.zip

    Thanks for the reply. I haven't used this computer until today, and the problem with firefox seems to have resolved itself as I can use it now on this computer prior to running the updated versions. Here are the new logs.

    Okay but the new versions found and removed more malware. ;)


    You are using an outdated and unsupported antivirus program: AVG Anti-Virus 7.1

    I strongly advise you to cleanup your Desktop. Remove eveything but links to run programs. Do not download and save programs here and defintely do not use it for long term storage. You need to keep ComboFix.exe here for now as we need it, but we will be removing it when we are finished with your cleanup. A cluttered Desktop is malware's playground and it can also cause performance degradation especially when you start saving large files here like you are doing.

    Uninstall the below old versions of software:
    J2SE Runtime Environment 5.0 Update 1 <-- old versions are security risks and allow the Vundo infection like you have.

    You have a master boot record virus that we need to fix.

    Please run the below

    Using Dr.Web CureIt

    After running it, immediately reboot.

    After reboot, please download the following & save to your Desktop


    GMER's MBR.exe
    • Double click on the MBR.exe file to run it.
    • A log will be produced & saved to the desktop, called MBR.log.
    • Attach this log to your next message.
    Now run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

    O20 - AppInit_DLLs: vdhgml.dll

    NOTE: HJT may popup an error about the AppInit_DLLs line. Ignore it and click OK to continue.
    After clicking Fix, exit HJT.



    Now we need to use ComboFix to remove a bunch of malware files.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below
    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

    Now run Ccleaner!


    Now goto this link Using MGtools and download the new version of MGtools.exe from the black bold print link in the first sentence. Overwrite your previous MGtools.exe file with this one.



    Then attach the below logs:
    • Dr.Web CureIt log
    • the MBR.log
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    I apologize that this reply has taken so long, but I have been out of town for the past week. Here are the logs, though the Dr. Web CureIt found and deleted two files, they are not listed on the log for some odd reason.

    Also, I had a MS Antispyware 2009 ad pop up, so I instantly went and removed it via the control panel, and I ran an updated Malwarebytes to remove that. AVG then detected yet more Vundo infections. The MB log is attached as well. I should note that I saved the log file prior to removing the files, which explains the "no action taken". Only one file, a .dll, required a reboot to clean.

    I noticed that my CureIt file is a .log rather than a .csv. It is also 2.13 MB, so I cannot attach it in it's current form. Is there an archive folder that would have the csv file?

    It does not really matter now anyway since your logs show that what I wanted to fix was fixed.

    Your logs are clean.

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
      • Delete the C:\combofix folder from combofix (if it exists)
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:
