Hello,

 

I have the exact same problem as this topic here: https://www.bleepingcomputer.com/forums/t/646983/ntuserlitelist-svcvmxexe-vmxclientexe-dataupexe-winscrexe/

Just like the user in the topic mentioned, MBAR stops responding once is hits the trojan and I'm unable to complete the scan.

This isn't my first rodeo on this site, so here's my logs. Thanks!

Hi CalvenG :)

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 BleepingComputer, 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 BleepingComputer'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? :)

Let MBAR run. Make sure all your other programs are closed, MBAR is the only program open and do not touch your computer while it is scanning, and I can tell you that it'll eventually go through.

Thank you for the quick reply Mr. Yoan, It took about 3 hours but it did finally complete the scan. Here's the log.

It would appear that i am no longer infected because the llssoft and ntuserlitelist folders containing the trojan  that i was unable to delete are no longer in (C:)/users/calve/appdata/local

Also, svcvmx.exe and vmxclient.exe no longer launch when i boot up my PC and my CPU usage is back to normal. I will however wait for your "All Clean" before i do anything else.

MBAR managed to cripple the main infection, but SmartService drops so many files on the system that we're not done with the clean-up yet :)

Next, you should now be able to install and run a scan with Malwarebytes.

j1Bynr2.pngMalwarebytes - Clean Mode
  • Download and install the free version of Malwarebytes
    Note: If you have Malwarebytes already installed, you don't need to install it again. Simply start from the next bullet point;
  • Once Malwarebytes is installed, launch it and let it update his database. You might have to click on the little arrow by Scan Status in the middle right pane for it to do so;
  • Once the database update is complete, click on the Scan tab, then select the Threat Scan button and click on Start Scan;
  • Let the scan run, the time required to complete the scan depends of your system and computer specs;
  • Once the scan is complete, make sure that the first checkbox at the top is checked (which will automatically check every detected item), then click on the Quarantine Selected button;
    • If it asks you to restart your computer to complete the removal, do so;
  • Click on Export Summary after the deletion (in the bottom-left corner) and select Copy to Clipboard. Paste the content in your next reply;

Good :) Now let's do a sweep with AdwCleaner and JRT.

zcMPezJ.pngAdwCleaner - Fix Mode
  • Download AdwCleaner and move it to your Desktop;
  • Right-click on AdwCleaner.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Accept the EULA (I accept), let the database update, then click on Scan;
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Cleaning button. This will kill all the active processes;
    MV5ejgW.png
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it;
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply;
iT103hr.pngJunkware Removal Tool (JRT)
  • Download Junkware Removal Tool (JRT) and move it to your Desktop;
  • Right-click on JRT.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Press on any key to launch the scan and let it complete;
    tLsXbWy.png
    Credits : BleepingComputer.com
  • Once the scan is complete, a log will open. Please copy/paste the content of the output log in your next reply;
Your next reply(ies) should therefore contain:
  • Copy/pasted AdwCleaner clean log;
  • Copy/pasted JRT log;
