Win32/Kryptik.E Trojan?

Discussion in 'Malware Removal' started by GatorsUF, Aug 26, 2008.

    My Nod32 AV found this trojan on my computer. It pops up every once in a while saying it found a file that is trying to do something and it puts it into quarantine. Seems Nod32 is doing a good job of containing it, but it doesn't seem to completely remove it. Also there is a Windows Security window that pops up and has the "block""Unblock""enable protections", the only button I can click is "enable protections" so i just close it.

    Any help would be great.

    Welcome to Major Geeks!

    Please follow the instructions in the below link and attach the requested logs when you finish these instructions.


    If something does not run, write down the info to explain to us later but keep on going.

    Do not assume that because one step does not work that they all will not.


    READ & RUN ME FIRST. Malware Removal Guide


    Note:

    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode. You can running steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:

    Starting your computer in Safe mode

    2. If you have problems downloading on the problem PC, download the tools on another PC and burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.

    Well I got through all of it but one section... ComboFix would not finish. I let it sit for about 4 hours yesterday and it got stuck on "Completed Stage_48" and it wouldn't continue from there. I restarted the computer and ran it again this morning and it still got stuck there. Doesn't sound good for me huh? Here are the other logs.

    If you haven't already, please disable the Guest account in User accounts.

    Run this: Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.

    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 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.
    Now download The Avenger by Swandog469, and save it to your Desktop.

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

    Also delete all files in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\Temp
    C:\Documents and Settings\%username%\Local Settings\Temp

    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 and also attach the log from Avenger.

    Be sure to tell us how things are running.

    It seems fine right now, but before thing were popping up randomly like "antivirus 2008 - buy now" which I know is not safe, then my Nod32 was saying it found some thing and quarantined them. So hopefully that will stop but here are my logs.

    Bummer....missed one.

    Use windows explorer to find and delete:
    C:\WINDOWS\system32\ebqpixiz.exe

    Now lets clean up from the scans:
    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.


    Tell me if you are having any other problems. :)
