    You have a rootkit infection. Please download The Avenger by Swandog469, and save it to your Desktop.

    * Extract+ avenger.exe from the Zip file and save it to your desktop

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    * 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.

    Now run Ccleaner to clean out only temp files and nothing else!

    You will need to boot to the Recovery Console to remove this infection.

    Now boot to the Recovery Console and run the fixmbr to clear a Master Boot Record infection that you have.

    You can read the below to help you do this:

    Then boot back into normal mode.

    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 logs:

    * C:\Avenger.txt
    * C:\MGlogs.zip

    Sadly, we are still not out of the woods.

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    * Run avenger.exe by double-clicking on it.
    * -Do not change any check box options!!

    Now run Ccleaner to clean out only temp files and nothing else!

    Why is ComboFix no longer on your desktop? If you have deleted it, please download it again to your desktop and run it.

    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 logs:
    * C:\ComboFix.txt
    * C:\Avenger.txt
    * C:\MGlogs.zip

    Hi Tim,

    Thanks for the help. Please find the attached logs.

    Combofix.exe was not on the desktop b'coz i ran the scans first time in safe mode as i was not able to perform any actions in normal mode. Now, attached logs are from normal mode.

    Thanks,
    Rakesh

    Just two other things that we can remove and then I think you will be good to go.

    * 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.

    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 logs:

    * C:\Avenger.txt

    Your temp folder needs cleaning out. Please run CCleaner to remove all the temp files.

    I suggest you be very careful with using P2P software.

    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 are useful as backup scanners.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 /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    5. 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.
    6. Go to add/remove programs and uninstall HijackThis.
    7. 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.
    8. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 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 ato create a new clean Restore Point.
    9. After doing the above, you should work thru the below link:
