Hi, recently i detected and tried removing adware.elex & adware.ghokswa with malwarebytes, but it keeps coming back. It hijacks my browser and places weird icons on my desktop that leads to other sites (have not clicked on them, properties address, inferred so). And also ever since, google chrome has been shutting down very often, with the error message of "user not found"

May i please be guided on how to properly remove it?


Attached are the txt files from FRST, as well as a screenshot of malwarebyte's detection.

Hi lucaslyh :)

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? :)

Please give me a few hours to review your logs and get back at you.

Meanwhile, can you please provide me the logs of all the tools you ran: Malwarebytes, AdwCleaner, JRT, etc. If you don't know where to find them, let me know.

Hi Aura, thank you for stepping up to assist me.

Attached are the requested files, hope they can make it easier to help solve this issue.

Side note: seems like whenever i use chrome, it closes after awhile with an error message of "C:/user not found", not sure if pointing this out makes any difference.

Are you able to take a screenshot of that error message, or give me the full path?

Hi Aura, apparently, the path leads to an empty folder which (if i recalled) was already there since OS istallation. Another thing is that when i search on chrome's searchbar after the browser hijack, it leads me to to a " choose an account " page for googledrive :

Is there by any chance any other userprofiles with let's say, the name(s): 1, 2, 3, 5, 6 and so on?

Also, we'll run a first FRST fix. After running it, one (or more) .zip files should be created on your desktop. Their name will be "DATE_TIME.zip", where the DATE and TIME will match the date and time at which the FRST fix was ran. Upload all of them to the link below please.

  • 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;

Thank you. Now we'll do a quick sweep with JRT and AdwCleaner.

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;

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;

Your next reply(ies) should therefore contain:

  • Copy/pasted JRT log;
  • Copy/pasted AdwCleaner clean log;

Hi Aura, As instructed , attached are the logs of JRT and Adwarecleaner.

Earlier on, there is a zipfile that was asked to be uploaded, should i delete that as well?
And something i just realised, when i open google chrome, the google URL seem to have an additional "index" that seem to be random whenever i start up chrome. Attached as screen shotted.

It's okay if you deleted the threats from the last scan, I wanted you to run Malwarebytes once more to see if it'll detect anything else. The folder that was detected in the previous scan didn't show up in any of your previous logs, so I was wondering if it has been created recently (after we ran AdwCleaner, JRT, Malwarebytes, FRST, etc.) or if it had always been there and the detection for that specific folder had been added recently in Malwarebytes' database.

And yes, you're free to create a new thread in this section and PM me the link :)

I don't really see any remants of Elex or Ghokswa on your system. The detection from the last Malwarebytes log was a firewall rule allowing a certain program to go through, but I cannot say which one (since it isn't listed). 

I would like to leave this thread open for another week. Can you run a new scan with Malwarebytes every day or so and if it detects something, post the log here? My suspicious is that there are some remnants on the system, that I cannot see with FRST, and that Malwarebytes update the database and add a new one from time to time, hence why there's still detections on your system, even though the main infection has been dealt with already.
