While you are waiting for the next qualified/approved malware removal expert helper to take on your case, even though you may have run the following Malwarebytes utility or its subsets, please carefully follow these instructions: Do not try any other cleaning of any kind after running the support tool. Use the computer as little as possible, or even better don’t use it at all except to check this topic and follow the instructions given.

First, Restart the computer.

Then do the following after restart.

WARNING: Do Not click the Repair System under Advanced unless requested by a Malwarebytes support agent or authorized helper

1. Download the Malwarebytes Support Tool.
2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.

Thank you.

Hello  @Sam1912 My name is Maurice. I will guide you. Let's keep these principles as we go along.

• Please attach the ZIP report cited above by my colleague Porthos.
• Removing pesky malware can be an involved set of tasks over separate runs. Have much patience. Follow my directions. 
• Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
• Only run the tools I guide you to.
• Do not run online games while case is on-going. Do not do any free-wheeling web-surfing.
• The removal of malware isn't instantaneous, please be patient.
• Cracked or or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
• Please stick with me until I give you the "all clear".
• If your system is running Discord, please be sure to Exit out of it while this case is on-going.

  Do these 2 steps so that ALL folders & Files are set to SHOW, plus also, Turn OFF Windows Fast start.

After you have submitted mbst-grab-results.zip

Let's do one scan with Malwarebytes Adwcleaner to check for adwares. Just before pressing that "scan" button, be sure that Chrome & Edge, or other web browser are Closed.

It will not take much time,

First download & save it
guide & download link

Then be sure to close all web browsers after the download & before launching the tool.

Then go to where the EXE file is saved. Start Adwcleaner.  Then do a scan with Adwcleaner

Guide article

Attach the clean log from Adwcleaner when all completed.

Hello again @Maurice Naggar and @Porthos i did everything told me to do, i did an adwcleaner scan and it found nothing after 2 scans, so i will attach the file that was requested me to, and wait for your response thanks in advance.

[Sam1912]

So sorry for the two same messages, i forgot to attach adwcleaner logs :D

[Maurice Naggar]

Thanks. I am guiding you. The Malwarebytes program is present and installed. Start Malwarebytes.

Next, click the small x on the Settings line to go to the main Malwarebytes Window.   Next click the blue button marked Scan.

 

When the scan phase is done, be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

>>>>>>      👉      You can actually click the topmost left  check-box  on the very top line to get ALL lines  ticked   ( all selected).         <<<<     💢

 

Please double verify you have that TOP  check-box tick marked.   and that then, all lines have a tick-mark

 

Then click on Quarantine  button.

 

Then, locate the Scan run report;  export out a copy;  & then attach in with your  reply.
See https://support.malwarebytes.com/hc/en-us/articles/360038479194-View-Reports-and-History-in-Malwarebytes-for-Windows-v4

 There is much more even after this.

[Sam1912]

Okay, thanks for your fast response, i've done the scan, put everything detected in quarentine and deleted everything, now i am attaching the log from the scan

[Maurice Naggar]

That is very helpful. We will do more scans, later. As a next step, I suggest the following:
This is for a scan with ESET Onlinescanner (free). ESET is a well-respected, well-known entity and tool. ESET Onlinescanner checks for viruses, other malware, adwares, & potentially unwanted applications.
This here you can start & once it is under way, you can leave the machine alone & let it run over-night. No need to keep watch once it starts the actual scan run.

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

It will start a download of "esetonlinescanner.exe"

• Save the file to your system, such as the Downloads folder, or else to the Desktop.
• Go to the saved file, and double click it to get it started.

 

• When presented with the initial ESET options, click on "Computer Scan".
• Next, when prompted by Windows, allow it to start by clicking Yes
• When prompted for scan type, Click on CUSTOM scan  and select C drive to be scanned
• Look at & tick ( select ) the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"
• and click on Start scan button.

Have patience. The entire process may take an hour or more. There is an initial update download.
There is a progress window display. You may step away from machine &. Let it be. That is, once it is under way, you should leave it running. It will run for several hours.

• At screen "Detections occurred and resolved" click on blue button "View detected results"
• On next screen, at lower left, click on blue "Save scan log"
• View where file is to be saved. Provide a meaningful name for the "File name:"
• On last screen, set to Off (left) the option for Periodic scanning
• Click "save and continue"
• Please attach the report file so I can review

[Sam1912]

Hello again Mr Maurice, yesterday the scan took about 3 hours to complete, i was busy doing some stuff so i decided to send it out today in case you were sleeping, hope it wasn't any problem, i today turned on my pc and it only oppened every single log from the temp folder, plus it seem the chrome_url_fetcher folder are created by brave, so the only thing my pc dows now its that basically opens every folder in temp folder and every .txt file, i will attach the ESET scan log and all the txt files that it opened. Thanks in advance.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted items from a system. This tool does not install. It is run on-demand.

This link is for the 64-bit version of MSERT.exe . Be sure you save the file first
https://definitionupdates.microsoft.com/download/DefinitionUpdates/safetyscanner/amd64/MSERT.exe

Upon completion of the save, Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well

Launch MSERT.exe
Accept the agreement terms of Microsoft
Select CUSTOM scan
Look on Scan Options & select CUSTOM scan & then select the C drive to be scanned.

Then start the scan. Have lots of patience. Once you start the scan & you see it started, then leave it be.

Once you see it has started, take a long long break; walk away. Do not pay credence if you see some intermediate early flash messages on screen display. The only things that count are the End result at the end of the run.
Again, any on-screen display about repeat 'infection' is not to be relied on. Ignore those.
We only rely on the end result that is on the log-report-file.

This is likely to run for many hours ( depending on number of files on your machine & the speed of hardware.)

The log is named MSERT.log

the log will be at

Windows\debug\msert.log
Please attach that log with your reply

It is normal for the Microsoft Safety Scanner to show 'detections' during the scan process on the screen itself.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

[Sam1912]

Hi once more Mr @Maurice Naggar i did the requested scan and i will attach the result to this post, thanks in advance

Sophos Scan & Clean

Download Sophos Free Virus Removal Tool and save it to your desktop.

• If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....
• Please close all other open applications and Do Not use your PC whilst the scan is in progress... This scan is very thorough so it may take several hours to complete, please be patient...

Double click the icon and select Run

Click Next

Select I accept the terms in this license agreement, then click Next twice

Click Install

Click Finish to launch the program

• Once the virus database has been updated click Start Scanning

If any threats are found click Details, then View log file... (bottom left hand corner)

 

Attach the results in your next reply

• Close the Notepad document, close the Threat Details screen, then click Start cleanup

Click Exit to close the program

 

If no threats were found please confirm that result...

• The Virus Removal Tool scans the following areas of your computer:
• Memory, including system memory on 32-bit (x86) versions of Windows
• The Windows registry
• All local hard drives, fixed and removable
• Mapped network drives are not scanned.

Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

 

Saved logs are found under this sub-folder: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs 

Please attach that log on your next reply

Thank you

[Sam1912]

I'm more than glad to hear that some threats were removed, thanks @Maurice Naggar for your help, however, i was trying to download Sophos Free Virus Removal Tool but i can't, the email for the further validation required to download the tool never arrives.

 

[Maurice Naggar]

You ought to check the Junk or Spam folders of your email account.  Anyhow, we can skip the Sophos, and use another scanner.

One other scan here.

TrendMicro HouseCall scan
from this Link

First, Download & Save to your Downloads folder the appropriate HouseCallLauncher
Once the download is complete, go to where the Housecalllauncher is saved & double-click it to start it.

The program will check with TrendMicro & do a update run.

Next it will show the Disclosure window.

Click Next to proceed.

The end user license agreement is presented.   Click the Accept radio button & click Next to proceed.

I suggest a CUSTOM scan on C drive.

IF you wish a Full scan or a Custom scan, first click on the Settings

then you can select which drives you want to include in the scan.

The default is a Quick scan.

Click Scan now when ready.

The scan progress will then be displayed.   Monitor the progress or just leave it alone until it finishes this phase.

When the scan phase has completed, if any items are tagged, you will see a list, showing  the file & its location, the classification of the threat, the type, risk, and Action option.

If you see an item that you know is safe, you can click the Action  , and select Ignore.

When all done & ready, click the Fix now button.
The "Summary" at the end at "Review Results" is what matters.

[Sam1912]

Hello Mr @Maurice Naggar i did the scan and took more than 300 minutes, at the end of the summary it said that there weren't any infected files, i don't know if theres some log you may need, if there is please tell me the location of the file and i will get it, thanks once more.

 

[Maurice Naggar]

Very glad to read that TrendMicro Housecall reported no threats. That is re-assuring.

Now a different scan with another security scanner. 

You should first Close as many of your open-user app-screens as possible. That is to say, Exit all that you do not need to have open.

This with Kaspersky KVRT tool.

Download Kaspersky Virus Removal Tool (KVRT) from here: https://www.kaspersky.com/downloads/thank-you/free-virus-removal-tool and save to your Desktop.

Next, Select the Windows Key and R Key together, the "Run" box should open.



Drag and Drop KVRT.exe into the Run Box.



C:\Users\Sam\DESKTOP\KVRT.exe will now show in the run box.



add

-dontencrypt

Note the space between KVRT.exe and -dontencrypt

C:\Users\Sam\DESKTOP\KVRT.exe -dontencrypt 

should now show in the Run box.



That addendum to the run command is very important.


To start the scan select OK in the "Run" box.



The Windows Protected your PC window "may" open, IF SO then select "More Info"



A new Window will open, select "Run anyway"



A EULA window will open, tick both confirmation boxes then select "Accept"



In the new window select "Change Parameters"

 

• In the new window ensure the following boxes are ticked:
  • System memory
  • Startup objects
  • Boot sectors
  • System drive

• Then select "OK" and „Start scan“.

The Kaspersky tool is very thorough so will take a considerable time to complete, please allow it to finish. Also while Kaspersky runs do not use your PC for anything else..

• completed: If entries are found, there will be options to choose. If "Cure" is offered, leave as it is. For any other options change to "Delete", then select "Continue".
• Usually, your system needs a reboot to finish the removal process.
• Logfiles can be found on your systemdrive (usually C: ), similar like this:

Reports are saved here C:\KVRT2020_Data\Reports and look similar to this report_20230913_203000.klr

• Right click direct onto those reports, select > open with > Notepad.
• Save the files and attach them with your next reply

[Sam1912]

Hello, good afternoon/night Mr @AdvancedSetup, so grateful about your help and your kinds support, I really appreciate it, however I think there will be no need to do this scan and log exhaustive checking, for that reason even though it might be good to check just to be sure I decide to not do it because all problems that were bothering me and all the information people with not good intentions could try to reach are no longer in my pc or in any place because for extra security I deleted it with a secure file eraser so it won't leave any traces behind, once more thanks for your support and for be actively checking threads like this that haven't been consistently finished or closed, have a good day/night

[AdvancedSetup]
