Poweliks still infecting after rootkit removal

Recommended Posts

Hello!

After a frustrating day trying to create a user here, the system finally sent me a confirmation email!!

Anyway, I have a friends PC that MWB rootkit scanner found the Poweliks trojan and I ran the clean function several times, even in safe mode, but everytime I run it to check that it cleaned it, it's still showing up as infected? I ran Hitmanpro, combofix and adwcleaner as well as the regular malwarebytes scanner and it comes up clean, but the rootkit scanner says it's still present.

I installed FRST64 and created the log files which i have attached.

Any help would be greatly appreciated.

Thanks VERY much!

Tom

Hi Tomdee :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.

  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
  • As long as I'm assisting you on Malwarebytes Forums, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against Malwarebytes Forums's rules
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread


This being said, it's time to clean-up some malware, so let's get started, shall we? :)

I see that your friend is still using Malwarebytes Anti-Malware 2.2.1. Can you uninstall it, then install the latest version (Malwarebytes 3.3.1), run a scan, delete what it detects and provide me the log afterwards?

Thanks for the response!

 

I have installed the latest version of MWB, activated the rootkit scan and ran the scan and it found the Poweliks Trojan again. I quarantined it and did the delete on reboot, re-scanned and the log is attached. The delete on reboot did NOT remove it.

I await your further instructions.

Thanks

Tom

Ok, I ran the MBAR and it came up clean, so I rebooted to see if it came back and it did. I didn't delete it but instead ran the FRST64 app and the results are below. I have also included a screen shot of the MBAR window. This is nuts! I cannot remember anything so stubborn since the Stoned Michaelangelo virus in the 90's!

Thanks again.

Here's the full string from MBAR window.

Let's try something. Not sure it'll work but it's worth a shot. Run a scan with MBAR first to make sure the detection is still there, but do not delete it.

EndqYRa.pngSWReg.exe
Follow the instructions below to perform a Registry fix using SWReg.exe

  • Download swreg.exe and save the file on your Desktop;
  • On Windows Vista & 7, click on the Windows Start Menu, then enter cmd in the search box, right-click on the cmd icon and select Spcusrh.pngRun as Administrator
  • On Windows 8, drag your cursor in the bottom-left corner, and right-click on the metro menu preview, then select Command Prompt (Admin);
  • On Windows 8.1, right click on the Windows logo in the bottom-left corner and select Command Prompt (Admin);
  • Enter the command below and press on Enter;
    cd "%userprofile%\Desktop"
  • You will now be in your Desktop folder (the command prompt will show C:\Users\$USERNAME\Desktop);
  • Enter the command below, and press on Enter:
    SWReg NULL QUERY HKU\S-1-5-21-3514624900-2102147923-1103798338-1113_Classes\CLSID\{AB8902B4-09CA-4BB6-B78D-A8F59079A8D5} /s
  • It will tell you that a null-embedded key was found, and asks you if you want to delete it. Enter y and press on Enter;
  • On success, it should return you the Scan complete message, let me know if it did or not;
