I have a malware in my computer. Techextreme tried to help me in this thread:
http://www.bleepingcomputer.com/forums/t/306163/need-help-with-a-virus/
but he couldn't remove it.
I was doing your preparation guide and downloaded DDS but my computer says it is an Autocad script and when I double-click on it, it opens in a notepad window.
So orange blossom told me to run RSIT and I've attached its log.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below I will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

GMER doesn't run on the infected computer. And when I try to boot into Safe Mode the computer crashes.

Okay I think TechExtreme is referring you for a more powerful tool to be run.

Please download exeHelper to your desktop.
Double-click on exeHelper.com to run the fix.
A black window should pop up, press any key to close once the fix is completed.
Post the contents of exehelperlog.txt (Will be created in the directory where you ran exeHelper.com, and should open at the end of the scan)
Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).


Then rerun RKill

Download and Run RKill

Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

Link 1
Link 2
Link 3
Link 4
  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • Please post the resulting log in your next reply.


Then run Combofix

Please download ComboFix from one of these locations:* IMPORTANT !!! Save ComboFix.exe to your Desktop making sure you rename it comfix.exe
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.



Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:



Click on Yes, to continue scanning for malware.


Thanks thumbup2.gif
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

  • 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.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • Under the Standard Registry box change it to All.
  • Check the boxes beside LOP Check and Purity Check.
  • Please copy the following into the Custom Scans box at the bottom

    CODE
    /md5start
    eventlog.dll
    scecli.dll
    netlogon.dll
    cngaudit.dll
    sceclt.dll
    ntelogon.dll
    logevent.dll
    iaStor.sys
    nvstor.sys
    atapi.sys
    IdeChnDr.sys
    viasraid.sys

    viamraid.sys

  • Now click the Run Scan button on the toolbar.

This is a puzzle. There is clearly intervention stopping .exe files running but the OTL log suggests that there isn't.

Have you tried MBAM using this method:

Please download Malwarebytes Anti-Malware and save it to your desktop.

Please open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the name to mblah and the .exe extension to .bat, .com, .pif, or .scr

Then try and run it.

When I click on the link to MBAM on the infected computer the browser closes. When I click on the link from another computer the link appears to be wrong.

Please check for two specific rootkits with these small programs

Download and run HAMeb_check.exe
Post the contents of the resulting log.


Then

Please save this file to your desktop. Click on Start->Run, and copy-paste the following command (the bolded text) into the "Open" box, and click OK.

"%userprofile%\desktop\win32kdiag.exe" -f -r

When it's finished, there will be a log called Win32kDiag.txt on your desktop. Please open it with notepad and post the contents here.

Looks like the Max++ rootkit

You must first verify that you can logon to the Windows Recovery Console.
To do so, you must have the Recovery Console installed or use the Windows XP installation cd.

How to install and use the Windows XP Recovery Console


Next, please download maxlook, saving the file to your desktop.
Double click maxlook.exe to run it. Note - you must run it only once!
As instructed when the tool runs, restart the computer and logon to the Recovery Console.
Execute the following bolded command at the x:\windows> prompt <--- the red x represents your operating system drive letter, usually C

batch look.bat




You will see 1 file copied many times then return to the x:\windows> prompt.
Type Exit to restart your computer then logon in normal mode.
Please run maxlook.exe again now. Note - you must run it only once!
It will produce looklog.txt on the desktop and open it.
Please post the results here.

Hi,

I have not had a reply from you for 3 days. Can you please tell me if you still need help with your computer as I am unable to help other members with their problems while I have your topic still open. The time taken between posts can also change the situation with your PC making it more difficult to help you.

If you like you can PM me.

Thanks,


m0le
