    I've seen other threads about these kind of problems but didn't want to do anything in those incase it messed up the PC or something.

    Not sure how exactly I ended up with this but.. I use firefox anyways.

    Also I couldn't post a combofix log, seems when I try and run it, after completing the 50 stage scan it gets to a point where it says "Deleting files" and the computer then goes to a BSOD (Too quick to even read what it says) Before restarting itself and leaving no log or anything.

    Welcome to Major Geeks!



    Your infection is in your Master Boot Record (MBR). We need to see the below log before creating a fix.
    • Download bootkit_remover.rar
    • Click the underlined DOWNLOAD text to download the file and save it to your Desktop.
    • You then need to extract the remover.exe file from the RAR using a program capable of extracing RAR compressed files. If you don't have an extraction program, you can use 7-Zip
    • After extracing remover.exe to your Desktop, double click the remover.exe file to run the program.
    • Attach or post inline here, the output from remover.exe
    NOTE: The Command Prompt window text can be copied to the clip board by right clicking on the top bar of the window and using the Edit commands to Mark, Copy, and Paste.


    Also I need to ask some questions:
    1. Do you have any drives that has a non-windows installation on them
    2. Are all drives NTFS formatted
    3. Do you have any non-standard or special MBRs which can occur from companies like Dell or HP who frequently install additional partitions used for recovery partitions in lieu of giving CD/DVDs.
    4. Is any program like Grub ( see:http://www.gnu.org/software/grub/ ) being used
    5. Is drive-encryption being used?
    6. Are any drives external USB pen drives or external hard drives being used?
    7. VERY IMPORTANT: Do you have all important data backed up? You really should do this before continuing since we will need to rewrite your MBR to fix this and while most times this can be done without any problem, these infections can react badly and that could result in a PC not being bootable. You really don't have much choice though since these infections are too dangerous to your security to leave on a PC.

    • Click Start, Run then copy and paste the below into the Run box and click OK.
    "%userprofile%\Desktop\remover.exe" fix \\.\PhysicalDrive0
    • Now reboot your PC and after reboot continue with the below instructions.
    • Disable System Restore on all drives.
    • Look for the below folder and if if it sill exists, delete it.
      • C:\System Volume Information\Microsoft
    • Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).
      Then attach the below logs:
      • C:\MGlogs.zip

    Well first off i'll say thanks for the help so far.

    I carried out the instructions you gave in the last post, but wasnt able to delete
    C:\System Volume Information\Microsoft (Not sure if it's even there anymore, couldn't open System Volume Information since it's apparantley inaccessible, but hovering over the System Volume Information folder states that it's empty)

    Still, following the other steps you posted, the computer seems to be ok now, haven't seen any of the previous problems reoccurring (yet anyway, hoping it's gone)

    Anyway, here's the requested MGlogs log

    You're welcome.

    You need to stop using MSconfig to control startups as stated in step 4 of the READ & RUN ME. Put your PC into Normal Startup mode. Re-read this to see proper methods of controlling startups.

    Is XfireXO Toolbar something you knowingly installed and use?


    Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.



    I see the below from StopZilla which it appears you have uninstalled. Delete the below is StopZilla is no longer used.
    C:\Documents and Settings\All Users\Application Data\STOPzilla!
    C:\SZKGFS.dat
    C:\WINDOWS\system32\drivers\kgpcpy.cfg

    Uninstall the below software:
    Ask Toolbar
    J2SE Runtime Environment 5.0 Update 5
    Java(TM) 6 Update 16
    Java(TM) SE Development Kit 6 Update 13
    Java(TM) SE Development Kit 6 Update 6

    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:

    O2 - BHO: (no name) - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - (no file)
    O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
    O2 - BHO: (no name) - {A057A204-BACC-4D26-9990-79A187E2698E} - (no file)
    O3 - Toolbar: (no name) - {A057A204-BACC-4D26-9990-79A187E2698E} - (no file)

    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.
    • 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 has expired or need to be updated to a new version, make sure you allow it to update.
    • 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

    Also delete all files and subfolders in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\Temp
    C:\Documents and Settings\Owner\Local Settings\Temp

    Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    Now download the current version of MGtools and save it to your root folder. Overwrite your previous MGtools.exe file with this one.

    Run MGtools.exe ( Note: If using Vista or Win7, make sure UAC is still disabled. Also don't double click on it, use right click and select Run As Administrator )

    Now attach the below log:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Well I followed your instructions in the previous post, and got up to the point where I had to use that .txt script to run Combofix.

    However when I do that, and after ComboFix actually starts running, once again the computer just goes to a quick BSOD and restarts itself, without leaving any sort of log or completing the process.

    I tried to run ComboFix in that way 3 times, and the result was the same everytime.

    Okay then instead of using ComboFix, let's do it this way.



    Now download The Avenger by Swandog46, 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.

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

    Also delete all files in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\TEMP
    C:\Documents and Settings\Owner\Local Settings\Temp

    Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

    Now download the current version of MGtools and save it to your root folder. Overwrite your previous MGtools.exe file with this one.

    Run MGtools.exe ( Note: If using Vista or Win7 make sure UAC is still disabled. Also don't double click on it, use right click and select Run As Administrator )

    Then attach the below logs:
    • C:\avenger.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Ok, well I carried out the instructions you posted and there are the requested logs. Also, when I navigated to

    C:\Documents and Settings\Owner\

    myself manually there was about 10 .exe files with a random string of numbers .exe with the publisher listed supposedly as "Black internet virus" so i deleted them manually myself and then ran Ccleaner

    You're 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" /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 oof 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:
