    Howdy! It seems I have joined the growing number to be infected by this nasty little bugger that mutes the sound and causes multiple iexplorer.exe's to run in the background. While I have seen other people complain of pop-ups this has only happened about twice. I started to notice it about 3 days ago.

    I have performed (to the best of my ability) all of the required tests and logs and they are attached accordingly.

    The basics:
    I'm on a Dell, Windows XP, 32 bit...she's about 6 years old but is the most reliable computer I've ever had (knock on wood).

    Additionally, I noticed one of the scans picked up a hidden monstrosity of a file in my c:/ called hiberfil.sys that sucks up about 770mb of space....a) what is it? b) is it safe and c) can it be removed.

    Either or your help as always is much appreciated - the work yall do is great to help idiots like me. Holler if yall need anymore information.

    Thanks again and gig 'em!

    *** This is not a bump!*** I saw that you had asked others for the bootkit log...to save you the time in asking here is mine:

    Bootkit Remover version 1.0.0.1
    (c) 2009 eSage Lab
    www.esagelab.com

    Also I have no special partitions or multiple drives or anything like that...and yes, all my data is backedup. Thanks again!

    \\.\C: -> \\.\PhysicalDrive0
    MD5: aac7d8a98e39dfde27285ef395e66821

    Size Device Name MBR Status
    --------------------------------------------
    37 GB \\.\PhysicalDrive0 Unknown boot code

    Unknown boot code has been found on some of your physical disks.
    To inspect the boot code manually, dump the master boot sector:
    remover.exe dump <device_name> [output_file]
    To disinfect the master boot sector, use the following command:
    remover.exe fix <device_name>


    Press any key to quit...

    Welcome to MajorGeeks, jstue02s

    We have a better tool to use now - let's double-check with it

    Please also download MBRCheck to your desktop
    • Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
    • It will show a Black screen with some information that will contain either the below line if no problem is found:
      • Done! Press ENTER to exit...
    • Or you will see more information like below if a problem is found:
      • Found non-standard or infected MBR.
      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
    • Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
    • MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
    • Attach this log to your next message.

    Then run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Windows 7, use right click and select Run As Administrator).

    Please attach the new C:\MGlogs.zip and the MBRCheck_07.16.10_xx.xx.xx.txt files to your next reply.

    Please see the below link to disable TeaTimer:
    How to disable Spybot's TeaTimer

    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.

    Also note if you have a Dell PC which uses a non-standard MBR ( or another manufacturer's who does similar to Dell) , fixing the mbr may prevent access the the Dell Restore Utility, which allows you to press a key on startup and revert your computer to a factory delivered state. There are a couple of known fixes for said condition, though the methods are somewhat advanced. If you are unwilling to take such a risk, you should not continue but you risk serious problems leaving this infection in place and thus your only other option would be to try using the Dell Restore Utility to return a factory ship state which will remove everything you additional you have put onto the PC.


    Now if you wish to continue and fix the malware - please do the following:
    • Run MBRCheck.exe
    • Wait until you see the following lines:

      • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
      • Options:
        [1] Dump the MBR of a physical disk to file.
        [2] Restore the MBR of a physical disk with a standard boot code.
        [3] Exit.
        Enter your choice:
    • Please push the 'Y' key and then press Enter
    • When the program asks you to Enter your choice: enter 2 to Rstore the MBR and press the Enter key
    • Now the program will ask you to "Enter the physical disk number to fix (0-99, -1 to cancel):"
      • Enter X and press the Enter key.
    • The program will show Available MBR codes as below
    • You need to select your version of Windows frrom the list. For example, enter 0 or 1 for XP or enter 3 for Vista.....etc. and then press Enter.
    • The program will prompt for confirmation. Type 'YES' and hit Enter.
    • Left click on the title bar (where program name and path is written). From menu chose Edit -> Select All
    • You will see all the text in the window get highlighted.
    • Hit the Enter key on your keyboard to copy all of the text into the clipboard.
    • Paste that text into Notepad, save it to your desktop as MBRfix.txt
    • Restart your PC.
    • Attach the MBRfix.txt file to your next message..

    (the problem still persists as well)

    Let's go further then do a double-check, jstue02s.

    Step 1:
    Please look in Add/Remove Programs for the following and uninstall if found. If you get any errors just make a note and continue on.
    b]Step 2:[/b]
    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:
    After clicking Fix, exit HJT.

    Step 3: 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.
    • Make sure you have shut down all protection software (antivirus, antispyware, firewall...etc) programs so they do not interfere with the running of ComboFix. *Remember to re-start them before coming back online.
    • 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 inside of the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):
    • 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
      [​IMG]
    • 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.


    Step 4:
    Now using Windows Explorer - find and delete
    D:\Setup.exe

    Step 5:
    Open CCleaner - select "Cleaner" > "Run Cleaner" <---use this function ONLY!

    Step 6:
    * So I can double-check, please run the steps again from my post #6.

    Please attach the new C:\MGlogs.zip and the MBRCheck_07.16.10_xx.xx.xx.txt files to your next reply.

    How is your machine running?

    Then re-run the MBRCheck.exe and attach that log as well.
