    Hello,
    4 days ago AVG detected Trojan horse dropper.generic_c.mmi on my computer.:cry
    I succeeded in removing the Trojan using Hitmanpro and have not received any new alerts or warnings.
    While verifying that the trojan had indeed been removed I was alerted by Roguelkiller that my pc was infected by [Rootkit] ZeroAccess (Max++).
    I ran tdsskiller which detected nothing and combofix which did not remove the infection.:confused
    All steps have been completed from Vista and Win 7 Malware Removal/Cleaning Procedure.
    Could one of you kind soles have a look at my situation ?

    many thanks

    NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

    Attached is fixlist.txt
    • Save fixlist.txt to your flash drive.
    • You should now have both fixlist.txt and FRST64.exe on your flash drive.

    Now re-enter System Recovery Options.
    Run FRST64 and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (How to attach)

    Now attempt to boot normally.

    ------------------------------------

    • Now run FRST again, no fix, just a scan and attach the log.
    • Also re run RogueKiller, again, no fix, just a scan and attach log.
    • How are things running?

    No worries. ;)


    Tiny little bit to do.

    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.

    Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.


    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:
