    Hello All,
    I work as a re-seller for a Point-Of Sale software. Today I noticed the same rootkit infection on 5 workstations, in different areas and on seperate networks.
    Present on all machines,:
    1.System Restore wll not toggle following a succesful combofix rootkit removal
    2. Services.msc, Gpedit.msc the menus appear blank, defaulting to the extended (Screen included)
    3.MBAM '375' error (Failed to load control vbalgrid from vbalsgrid6.ocx) none of the fixes from malwarebytes.org work.
    4. sfc /scan and fixmbr does nothing.
    5. Network services are gone. attempting to manually toggle them on results in errors (Screen included) Print services are gone.
    6. You cant copy or paste anything (makes posting logs a pain)

    I also might be crazy but I think this infection is intelligent. After running RootRepeal and some other rootkit tools the cd_rom stopped working and when I attempt to plug in my USB drive & browse, The machine attempts to format it.
    (Screen included)

    The only thing all these machines have in comon, is that they are all Windows XP Professional machines with Service Pack 3. & (lol) have McAfee Total Protection installed. I should also note in Services.msc, you cant stop the McAfee services.

    This is obviously for a business so while I will be happy to clean this single computer, I am not prepared to clean out all of the other machines that are affected. This is something that the IT department are paid to do.

    Please go to Add/Remove programs and uninstall the following software:

    • Java(TM) 6 Update 17

    Now we need to use ComboFix
    • 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 quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    Fcopy::
    C:\WINDOWS\$NtServicePackUninstall$\svchost.exe | c:\windows\System32\svchost.exe
    
    Driver::
    odnns
    
    File::
    c:\windows\isRS-000.tmp
    c:\windows\System32\drivers\kqovo.sys
    C:\Documents and Settings\NetworkService\Local Settings\Application Data\52U3eMsv42W25
    C:\Documents and Settings\NetworkService\Local Settings\Application Data\B5XE5d7g
    C:\Documents and Settings\NetworkService\Local Settings\Application Data\JH40y5L
    C:\Documents and Settings\NetworkService\Local Settings\Application Data\yBQPLGaac1e5q
    C:\Documents and Settings\Owner\Local Settings\Application Data\yBQPLGaac1e5q
    C:\Documents and Settings\All Users\Application Data\52U3eMsv42W25
    C:\Documents and Settings\All Users\Application Data\B5XE5d7g
    C:\Documents and Settings\All Users\Application Data\JH40y5L
    C:\Documents and Settings\All Users\Application Data\yBQPLGaac1e5q
    
    • 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.


    Now download and run SUPERantispyware and Malware Bytes which you should have done before anything else.

    Reboot your machine and install the most current and up to date version of Java available here at the below link:

    Java Runtime 6

    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 logs from SAS and MBAM.

    Let me know how the machine is behaving.
