    Hi,

    Thanks for being here to help. I've had problems lately with pop-ups, contextual ads, etc. that seem to be caused by virtumonde/vundo. I did the cleaning procedures, and the logs are attached below. Two questions:

    1 - Is it really safe to trust my computer at this point, or do I need to format
    the disk?

    2 - I tried to install a new firewall and an error message told me that it was not
    a valid Win32 application. Not sure what that's about.

    Thanks for any help you can give.

    Any time you feel your system security has been compromised, you need to use a different computer and change all your password. Then be vigilant with your accounts.

    There is not much left to remove, so let's do this:

    Please follow the instructions here: Yoog Removal

    Now let's 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!
    o If it is not on your Desktop, the below will not work.
    * Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    
    File::
    c:\windows\system32\zohewigu.dll
    C:\WINDOWS\system32\jukajeyi.exe  
    C:\WINDOWS\system32\ziwemove.exe 
    
    RegLockDel::
    [HKEY_LOCAL_MACHINE\software\Classes\CLSID\{EC43E3FD-5C60-46a6-97D7-E0B85DBDD6C4}\InprocServer32]
    @DACL=(02 0000)
    @="c:\\windows\\system32\\zohewigu.dll"
    "ThreadingModel"="Both"
    
    
    * 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.
    If it asks you to overide the prvevious file with the same name, click YES.
    * Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    * 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.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Combo.

    When I put the CFscript into the ComboFix I was told that I did not have appropriate permissions to do that. I'm the administrator on my computer; I tried to do it in safe mode, but I can't get into safe mode anymore for some reason. Also, my computer no longer recognizes my dvd drive and won't allow me to install any new drivers. I'm really ready to just format my drive, my i'm not permitted to do that either. Thoughts? Thanks a bunch.

    Let's try resetting the permissions:

    The below is based on original info from http://support.microsoft.com/kb/949377

    Important: This task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

    How to back up and restore the registry in Windows]

    1. Download and then installSubInACL (SubInACL.exe)file from Microsoft.
    2. Click Start, Run and enter notepad and click OK to bring up the Windows Notepad program.
    3. Copy and then paste the following text into Notepad.

    Code:
    cd /d "%ProgramFiles%\Windows Resource Kits\Tools" 
    subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
    subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
    subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
    subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
    subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
    secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
    
    4. Save this Notepad file as Reset.cmd to your desktop. Be sure the Save as type is set to all files.
    5. Once you have save it properly, double-click the Reset.cmd file to run the script.

    * Note This script file may take a long time to run. Additionally, you have to run this script as an administrator.

    6. Now reboot your computer! You must do this before the above will take effect.

    After the reboot, let's see if you can run the Combo script:

    * Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    o If it is not on your Desktop, the below will not work.
    * Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    Code:
    KILLALL::
    
    File::
    c:\windows\system32\zohewigu.dll
    C:\WINDOWS\system32\jukajeyi.exe  
    C:\WINDOWS\system32\ziwemove.exe 
    c:\windows\vpc32.INI
    
    RegLock::
    [HKEY_LOCAL_MACHINE\software\Classes\CLSID\{EC43E3FD-5C60-46a6-97D7-E0B85DBDD6C4}\InprocServer32]
    @DACL=(02 0000)
    @="c:\\windows\\system32\\zohewigu.dll"
    "ThreadingModel"="Both"
    
    RegLockDel::
    [HKEY_LOCAL_MACHINE\software\Classes\CLSID\{EC43E3FD-5C60-46a6-97D7-E0B85DBDD6C4}\InprocServer32]
    
    

    * 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.
    If it asks you to overide the prvevious file with the same name, click YES.
    * Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
    * 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.

    If for some reason it still won't run, then use windows explorer to find and delete those files.

    Now, the alternative is to download The Avenger by Swandog469, and save it to your Desktop.

    * Extract avenger.exe from the Zip file and save it to your desktop
    * Run avenger.exe by double-clicking on it.
    * Do not change any check box options!!
    * Copy everything in the Quote box below, and paste it into the Input script here: part of the window:


    * Now click the Execute button.
    * Click Yes to the prompt to confirm you want to execute.
    * Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    * Your PC should reboot, if not, reboot it yourself.
    * A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Avenger and or Combo.

    Neither the SubInACL.exe file nor the Avenger program will install. They download, but don't install. I've tried to install other programs, but since i did the read and run first i haven't been able to install anything.

    Then you will have to remove those items manually. Use windows explorer to find and delete:
    c:\windows\system32\zohewigu.dll
    C:\WINDOWS\system32\jukajeyi.exe
    C:\WINDOWS\system32\ziwemove.exe
    c:\windows\vpc32.INI

    Tell me if you are able to do that.

    Then re-run Combo and run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file and the Combo log.
