  1. I was told by one of the posters in the OS forum to post in this one. I need help getting rid of this. They say I'm infected by it, but I can't find this file ANYWHERE on my computer. I did everything I was told to.

    Here is the link to my original thread:

    Hello and welcome to Techspot.

    Your system is infected with a password stealing Trojan.

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.

    Download the AVG Antirootkit programme. Disconnect from the net and install the programme, then restart your computer.

    Run the programme and click the click "Perform in-depth search." Allow AVG to complete the scan. The AVG scanner will give the "Rootkit path"
    * Select the Rootkit Driver by placing a checkmark against it and click "Remove selected items." Next, agree for the terms and conditions that is displayed by AVG and click "OK" to reboot the PC. Reconnect to the net.

    Download and run the Blacklight programme. Follow all the instructions carefully.


    Then, go and read the Viruses/Spyware/Malware, preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT and AVG Antispyware logs as attachments into this thread, only after doing the above.

    Let me know the results of the rootkit scans.

    Regards Howard :wave: :wave:

    I ran everything as I was told. The AVG rootkit picked up three files named mssync20 (.sys, .exe, and one more) so I deleted those. It also said to delete IEXEPLORE.EXE so... I did. I was able to find another iexplore.exe in the C:\WINNT so I could get back to using Internet Explorer (I also have firefox installed). I now have errors in my event log:


    Event ID: 7000
    The mssync2020 service failed to start due to the following error:
    The system cannot find the file specified.

    Event ID: 10000
    Unable to start a DCOM Server: {0002DF01-0000-0000-C000-000000000046}. The error:
    "The system cannot find the file specified. "
    Happened while starting this command:
    "C:\Program Files\Internet Explorer\iexplore.exe" -Embedding

    Event ID: 10010
    The server {1BE1F766-5536-11D1-B726-00C04FB926AF} did not register with DCOM within the required timeout.

    I have also attached the two logs.

    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.

    Delete all files in AVG Antispyware quarantine.

    Click start/run and type services.msc into the run box and press the enter key.

    When the window appears, maximise it. Double click on the following services(if there) and select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

    mssync20

    Close the services window.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).

    mssync20.exe

    Close task manager.

    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).

    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page = C:\windows\system32\blank.htm

    R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page = C:\windows\system32\blank.htm

    O4 - HKLM\..\Run: [mssync20] C:\WINNT\system32\mssync20.exe

    O4 - HKLM\..\RunServices: [mssync20] C:\WINNT\system32\mssync20.exe

    O4 - HKCU\..\Run: [mssync20] C:\WINNT\system32\mssync20.exe

    O4 - HKCU\..\RunServices: [mssync20] C:\WINNT\system32\mssync20.exe

    O20 - AppInit_DLLs:

    Click on the fix checked button.

    Close HJT.

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

    C:\WINNT\system32\mssync20.exe
    C:\windows\system32\blank.htm

    Reboot into normal mode and rehide your protected OS files.

    Post a fresh HJT log and let me know if you`re still having problems.

    Regards Howard :)

    I was unable to locate the blank.htm in the windows directory because I do not have a windows directory! I also ran the Hijack this and deleted the ones you told me to in safe mode. Here is a refresh hijack this log. It looks like it is still there. ARGH

    Also, the event ID 7000 and Event ID: 10000 error is still happening.

    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 log.

    Regards Howard :)

    The Avenger did restart my computer the first time. I had to login (you didn't say a preference for non-administrator or not so I used my administrator account) and it popped up the command window.. did its thing.. the command window disappeared but the computer never rebooted. Attached is the hijack this log and avenger log.

    Your HJT log is now 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 :)
