infected with maleware

Recommended Posts

Hello all, 


i noticed for the past few days i could not use cmd so i did a scan with malewarebytes recently and found Registry Value: 1
Hijack.Shell, HKU\S-1-5-21-1025430842-2179429058-833570161-1000\SOFTWARE\MICROSOFT\COMMAND PROCESSOR|AUTORUN, No Action By User, [511], [451944],1.0.3383 i tried to remove it and the next time my computer restarted i just had a black screen with command prompt open. i had to restore the quarantined maleware to get my background and icons back on the next restart. i really don't know where to go from here so any help would be apreciated thanks.

Hi brandon27 :)

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? :)

Can you update your Malwarebytes database, run a new scan and provide me the log? No need to quarantine anything for now.

Alright :) I just need a bit more information, as I'm passing it along to the Research team so they can adjust the detection.

iO3R662.pngFarbar Recovery Scan Tool (FRST) - Fix mode
Follow the instructions below to execute a fix on your system using FRST, and provide the log in your next reply.

  • Download the attached fixlist.txt file, and save it on your Desktop (or wherever your FRST.exe/FRST64.exe executable is located)
  • Right-click on the FRST executable and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Click on the Fix button
  • On completion, a message will come up saying that the fix has been completed and it'll open a log in Notepad
  • Copy and paste its content in your next reply

Also, two files should be on your desktop afterwards: Winlogon.reg and Command.reg. Can you put them both in a .zip archive, and attach it here?

This is exactly the threat we were looking for.

PUM.Optional.CMDShell, HKU\S-1-5-21-1025430842-2179429058-833570161-1000\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\WINLOGON|SHELL, No Action By User, [14917], [464572],1.0.3390

Quarantine both detections, then restart your computer and see if it boots normally.
