    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.

    We will proceed...

    Thus for example with remover.exe on the Desktop and assuming the physicaldrive0.


    • Click Start, Run and copy and paste the below into the Run box and click OK.

    • Now reboot your PC and after reboot continue with the below instructions.
    • 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
    Make sure you tell me how things are working now!

    My wav volume hasn't muted at any point in the last 10-12 minutes. Everything seems to be in working order so far.

    Thanks a lot if this is all corrected.

    A little more remains to be done. Give me a minute and I'll post a fix.

    What are you using for anti virus currently???

    If you are not deliberately set up to use the following proxy then please include it in our below fixables:
    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    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.

    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::
    
    File::
    c:\windows\system32\drivers\etmgml.sys
    c:\windows\system32\drivers\klmdb.sys
    c:\windows\system32\drivers\txqfmv.sys
    c:\windows\system32\drivers\nfxccb.sys
    C:\WINDOWS\TEMP\100.dat
    C:\Documents and Settings\Administrator\Local Settings\temp\9e18c12c-1f7c-456d-a6b7-2e06f78a4372.dmp
    
    DirLook::
    C:\WINDOWS\yellowtail+1
    
    Folder::
    c:\documents and settings\LocalService\Local Settings\Application Data\AskToolbar
    c:\documents and settings\NetworkService\Local Settings\Application Data\AskToolbar
    c:\documents and settings\Administrator\Application Data\Viewpoint
    c:\documents and settings\All Users\Application Data\Viewpoint
    C:\Documents and Settings\Administrator\Local Settings\Application Data\hbfsanxks
    
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{3CA2F312-6F6E-4B53-A66E-4E65E497C8C0}]
    
    • 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

      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.

    Things still running good??

    Everything seems fine again. No iexplore.exe processes. No wave muting.

    To answer a question you asked earlier, I'm running Norton Security Suite, provided by comcast

    Okay, looking loads better.

    Now tell me what is contained within this folder:

    I think I shall be giving you final steps soon. :)

    Two files in that folder.

    scrub2k.exe
    scrub2k.ini

    Those files relate to Hewlett Packard. They are safe despite the strange (to me) named folder :-D

    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 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:
