  1. Hi,

    My home computer seems to have been infected with some malware.

    I've already gone through the preliminary instructions, and I attach the logs. Anti-rootkit showed nothing.

    Please help me on this? Thank you!!!

    Run this Symantec/Norton removal tool.

    1. Please download The Avenger by Swandog46 from HERE. Save it to your Desktop and extract it.

    2. Download the attached avengerscript.txt and save it to your desktop

    Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

    3. Now, start The Avenger program by double clicking on its icon on your desktop.

    Under "Script file to execute" choose "Load script from file".
    Now click on the folder icon which will open a new window titled "open Script File"
    navigate to the file you have just downloaded, click on it and press open
    Now click on the Green Light to begin execution of the script
    Answer "Yes" twice when prompted.

    4. The Avenger will automatically do the following:

    It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
    On reboot, it will briefly open a black command window on your desktop, this is normal.
    After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
    The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.

    5. Please attach the content of c:\avenger.txt into your reply, as well as a fresh HJT and Combofix log.

    Regards Howard :)

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    Run HJT with no other programmes open(except notepad). Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O2 - BHO: (no name) - {37140417-5cea-4738-a278-3ced75ee974d} - C:\WINDOWS\system32\cnetgae.dll (file missing)

    O20 - AppInit_DLLs: c:\windows\system32\ssqpmmj.dll

    O20 - Winlogon Notify: cnetgae - cnetgae.dll (file missing)

    O20 - Winlogon Notify: comerf - comerf.dll (file missing)

    O20 - Winlogon Notify: dminv32 - dminv32.dll (file missing)

    O20 - Winlogon Notify: linnel - linnel.dll (file missing)

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).

    c:\windows\system32\ssqpmmj.dll


    Reboot into normal mode and rehide your protected OS files.

    Regards Howard :)

    Your HJT log is clean.

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.


    If you have any further virus/spyware problems, please post in this thread.

    Regards Howard :)
