    Hi, I've got a computer that is running very slowly, I'd appreciate your help in cleaning it up.

    I came across a couple problems in running the scans. Running rootrepeal it gets partway in then comes up with a transparent error dialog box. When I click all around the box and find the button then rootrepeal closes.

    Running mgtools I get an error for processdll.exe, "Application has generated an exception that could not be handled".

    I also have about 10 unknown network devices listed in the device manager. Windows tries to install the drivers for them but seems to have problems. Trying to install one of them it came up with an error saying "Insufficient system resources..." Not sure if these are related to the malware.

    I did run superantispyware but I forgot to bring the log with me, I can attach it later.

    Thanks for your help!

    Please use add/remove programs to uninstall:
    Java(TM) SE Runtime Environment 6 Update 1

    * 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.
    * Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    * If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
    * 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:
    ClearJavaCache::
    KILLALL::
    
    File::
    C:\ProgramData\QWjxRDAgq6OZDJ
    C:\ProgramData\~QWjxRDAgq6OZDJ
    C:\ProgramData\~QWjxRDAgq6OZDJr
    
    
    * 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 previous 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.

    Note: If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.

    Now download and install:
    Java Runtime 7


    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below log:

    • C:\MGlogs.zip

    Make sure you tell me how things are working now!

    Thanks for the steps. I got the java updated and ran combofix with the script. When I ran the getlogs I still got the error for processdll.exe

    "Application has generated an exception that could not be handled.
    Process id=0xeb4 (3764), Thread id=0xcac (3244).

    Click ok to terminate the application.
    Click CANCEL to debug the application."

    I clicked ok


    You probably don't need it but I attached the old Superantispyware log too.

    It seems to be running ok, for an old computer :)

    I also noticed that when I run Windows Update and click the check for updates button it never finishes. It just says "Checking for updates..." and has the progress bar, but it never finishes. Not sure if it's related to any of this.

    Your logs are clean. I suggest two things:

    Post in the software forum for additional assistance with your update issues.

    Try this:
    There are so many possible causes of problems with Windows Update that it would probably be best to send you to the Software Forum. However, there are a few things we can try first.

    1. Make sure time and date and TimeZone are correct
    2. See if it works in safe boot mode
    3. Reset HOSTS file

    Download HostsXpert and then follow the below steps.

    • Unzip HostsXpert.zip
    • It will create a folder named HostsXpert in whatever folder you extract it to.
    • Run HostsXpert.exe by double clicking on it.
    • Click the Make Writeable? button. (if you only see a Make Read-Only selection, it is already writeable so skip this button).
    • Click Restore Microsoft's Hosts File and then click OK.
    • Click the X to exit the program


    4. flush DNS server

    Right-click on the Command Prompt icon and select
    "Run as administrator". Then type in: ipconfig/flushdns
    and press the Enter key on your keyboard.

    5. add Microsoft URLs to the Trusted Zone (see below)
    6. shutdown firewall and retry
    7. shutdown AntiVirus and try

    MS URLs

    http://*.update.microsoft.com


    http://download.windowsupdate.com


    http://genuine.microsoft.com


    http://go.microsoft.com


    http://support.microsoft.com


    http://update.microsoft.com


    https://*.update.microsoft.com <--Notice the https designation.

    the first thing to always check for Windows Update problems! make sure that Automatic Updates is not turned off. It needs to be on and the service status needs to be Started and the Service type needs to be Automatic.


    Next fix:
    1. Disable Windows Update
    a. Click on start
    b. Click on all programs
    c. Click on accessories
    d. Click on Run
    e. Type services.msc and press ok
    f. Right click on "Windows Update"
    g. Click on stop (Windows Update is now disabled)
    2. Rename Software Distribution folder
    a. Navigate to: C:/Windows/
    b. Find the folder named: ?SoftwareDistribution?
    c. Rename that folder to something like ?SoftwareDistribution.old?
    d. Create a new folder called ?SoftwareDistribution?
    3. Enable Windows Update
    a. Click on start
    b. Click on all programs
    c. Click on accessories
    d. Click on Run
    e. Type services.msc and press ok
    f. Right click on windows update
    g. Click on start
    If you are unable to find Software Distribution Folder, follow these
    steps before #2 above.
    1. From the explorer window press the Alt key to view the file menu.
    2. Click Tools
    3. Select Folder Options
    4. Select the View tab
    5. Select ?Show hidden files and folders?
    6. Remove the selection from ?Hide protected operating system files?
    7. Click OK

    Restart your PC and you should be good to go!

    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 real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    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" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.


    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. 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.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of 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.

    10. After doing the above, you should work thru the below link:
