Need help with rootkit

By Serene
Jul 21, 2010
  1. Hi

    I think my PC has been infected with Antimalware Guard and Trojan Horse Agent 2.

    AVG quarantined some files. With instructions from some other websites, I've removed the following ahuruaxubeu.dll, mswyxtnd.dll & xtchevep.dll. But I think the rootkill is still there.

    I've tried to follow the 8 steps. The files from SuperAntiSpyware, GMER, DDS are attached. Somehow could not download Malwarebytes Anti-Malware.

    Would deeply appreciate some help here.

    Thanks

    Serene

    Note: If you have a previous version of TDSSKiller downloaded please delete it now and download a fresh copy using the links provided below

    Download TDSSKiller and save it to your Desktop.
    Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.
    Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

    If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
    When it is done, a log file should be created on your C: drive called TDSSKiller.txt please copy and paste the contents of that file here.

    Hi

    I've got TDSKiller running. Came back with the hidden service message. Hit enter. Cursor moves down to the next line and nothing happens after that.

    Hang? Or I just need to be patient? Will there be a message when done?

    Be patient.
    If it stays there and nothing happens end the process.

    Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.

    There are 4 different versions. If one of them won't run then download and try to run the other one.

    Vista and Win7 users need to right click Rkill and choose Run as Administrator

    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    * Rkill.com
    * Rkill.scr
    * Rkill.pif
    * Rkill.exe


    • * Double-click on the Rkill desktop icon to run the tool.
      * If using Vista or Windows 7 right-click on it and choose Run As Administrator.
      * A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
      * If not, delete the file, then download and use the one provided in Link 2.
      * If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
      * Do not reboot until instructed.
      * If the tool does not run from any of the links provided, please let me know.

    Once you've gotten one of them to run then try to immediately run the following.

    Now try to run TDSSKiller again.

    It didn't work.

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt"
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    Here are the 2 files.

    In the last 2 runs of ComboFix, I did not disable Avira as there was no instructions to do so. Will that have any impact?

    Mid-way thru the 3rd run, Avira pop up a Malware detected messsage on c:\windows\system32\drivers\bplekcl.sys

    Here is the log ...

    After this run of ComboFix, internet explorer could not start up and gave this error "Illegal operation attempted on a registry key that has been marked for deletion". Shutdown & start up again and was ok. Hope there is no other hidden problem.

    Looks good, but let's double check.
    Delete your GMER file, download fresh one and post new log.

    Hi

    I've a problem.

    I downloaded GMER and run it. It was ok but I've forgot to save it.

    Downloaded 2nd time and tried to re-run. But GMER stopped working.

    So sorry, I may have made a mess of things.

    Looks perfect :)

    Uninstall Combofix:
    Go Start > Run [Vista users, go Start>"Start search"]
    Type in:
    Combofix /Uninstall
    Note the space between the "Combofix" and the "/Uninstall"
    Click OK (Vista users - press Enter).
    Restart computer.

    ==================================================================

    Download OTL to your Desktop.

    * Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    * Under the Custom Scan box paste this in:



    netsvcs
    drivers32 /all
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll
    %systemroot%\system32\*.wt

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs



    * Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows: OTL.txt and Extras.txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.
