Recommended Posts

Hi THIRUNAVUKKARASU :)

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? :)

Follow the instructions in the thread below. Make sure to download the MBAR linked in it. Let me know if you're not able to launch it and run a scan.

If you manage to run a scan, delete everything it finds, and then copy/paste the content of the "mbar-log-TODAY'S-DATE.txt" log that is located in the MBAR folder here after.

These certificates aren't given by Microsoft. They are added by the malware (CertLock) and they are security vendor certificates that are added under the "Untrusted Certificates" list, which means that you cannot run any executable signed with one of these certificates. Hence why you couldn't run Malwarebytes beforehand.

Now we'll move on with an AdwCleaner and JRT sweep.

  • 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;

  • 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;

  • 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;

I received your logs via PM. 

Now, let's run a new scan with FRST and see if there's anything left to remove.
