I have a rootkit virus that I have been unable to remove after a couple of days of work. All anti-virus products are not functioning. The malware detects their presence and shuts them down and disables them from future use. Windows explorer was damaged, along with the windows update feature. I have been able to restore windows explorer, but the update service is still not functioning. Tried to use GMER.exe and the malware shut it down during the towards the end of the file scan. No logs were generated. I attempted to run DDS.scr and it closes with no txt file file generated. I tried to rename it to another name, and then run it with the same result. Any help would be appreciated.

I downloaded RootRepeal.exe and followed the instructions. About two minutes into the scan of files, the session suddenly closed unexpectedly. The only message in the report window was C:\hiberfil.sys Locked to the Windows API!. Rootrepeal.exe would no longer run (said I didn't have sufficient permissions), so I deleted the executable and changed teh settings to set the Disk Access slider to High. It still failed...in the same manner as before. I deleted the file and downloaded it again. I changed the name to tatertot.scr as suggested. It would start to load, but then it terminated and gave me the following dialog message: Could not load driver (0xc0000035)! What should I do now?

Did you try step 2 and step 3? Those are different scans as is this one:



Please download peek.bat and save it to your Desktop. Double-click on peek.bat to run it. A black Command Prompt window will appear indicating the program is running. Once it is finished, copy and paste the entire contents of the Log.txt file it creates in your next reply.

If you encounter a problem downloading or getting peek.bat to run, go to Posted Image > Run..., and in the open box, type: Notepad
  • Click OK.
  • Copy and paste everything in the code box below into the Untitled - Notepad.
@ECHO OFF
DIR /a/s C:\WINDOWS\scecli.dll C:\WINDOWS\netlogon.dll C:\WINDOWS\eventlog.dll C:\Windows\cngaudit.dll >Log.txt
START Log.txt
DEL %0
  • Go to File > Save As, click the drop-down box to change the Save As Type to *All Files and save it as "peek.bat" on your desktop.
  • Double-click peek.bat to run the script.
  • A window will open and close quickly, this is normal.
  • A file called log.txt should be created on your Desktop.
  • Open that file and copy/paste the contents in your next reply.

Well, I just booted the machine. Had it off since my last post, and am now responding from another computer. The malware has now corrupted the machine's svchost.exe file. I can login, see the desktop, but have very limited functionality. There is no task bar, and no start button -- just a thin gray line at the bottom of the screen. I examined the processes that were running on the unit, and no svchost.exe processes were found in the list. There were two new processes running instead that I had never seen before, and they were both called mscorsvw.exe. I booted into safe mode with cmd line support. The svchost.exe file is in the C:\windows\system32 directory, but it is not usable. There are permissions issues that do not allow it to be executed. I am not sure this is salvagable at this point, but I thought I would post again and get your thoughts.

I was able to get to a cmd prompt from task manager, and after killing explorer.exe I was able to delete the corrupted svchost.exe out of the c:\windows\system32 directory and replace it with a copy of svchost.exe from another machine that I wrote out to a CD. After I rebooted the computer, svchost.exe loaded again and the desktop was restored.

Win32Diag.txt Output:

This text file is sizable and cannot be pasted into the reply window. It is over 600KB in size, and it appears if may of the items are repeating throughout the file. Is there any other way that I can get it to you without having to break it apart? Sorry to be such a pain.

Just add the extra large text as an attachment and add it to this:


Now that you were successful in creating those two logs you need to post them in our HJT forum There they will help you with the removal through some custom scripts and programs that we cannot run here in this forum

First, try to run a DDS / HJT log as outlined in our preparation guide:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

If it won't run, don't worry, just give a brief description and tell them that these logs were all you could get to run successfully

Post them here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

The HJT team is extremely busy, so be patient and good luck

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/264487/rootkit-infection-continued/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks from posting date perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
