Hello @soevel and :welcome::

While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

  1. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
  6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
  7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have sent.

Thank you.

Hello @soevel
My name is Maurice I will guide you. If you would look on the Malwarebytes report, you will see in Dutch the notations 

Geen actie door gebruiker


which translate in English to

No action by user


What that means is that you did not TICK (select) all of the detections of Hijack.AutoConfigURL.PrxySvrRST
Now do the following so that all the detections are removed to Quarantine.

Do a new scan with Malwarebytes for Windows.

Do a Check for Update using the Malwarebytes Settings >> General tab.

See this Support Guide https://support.malwarebytes.com/hc/en-us/articles/360042187934-Check-for-updates-in-Malwarebytes-for-Windows

When it shows a new version available, Accept it and let it proceed forward.  Be sure it succeeds.

If prompted to do a Restart, just please follow all directions.

Let me know how that goes.    Next, the Malwarebytes sca

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.

AFTER that has been completed, NEXT:

I would like a fresh report set for review. This is a report only.

Please download MALWAREBYTES MBST Support Tool

Once you start it click Advanced >>> then Gather Logs

Have patience till the run has finished.
Upload an archive once it is done. Attach the mbst-grab-results.zip from the Desktop to your reply..

Next action steps:
( 1 )
Take these actions so that Windows 11 is set to show all hidden files and folders.
Open File Explorer from the taskbar.

Select View > Show > Hidden items.

Select View ShowFile name extensions

( 2 )
Next first step, is to "Turn OFF ( to DISABLE) the "fast starup" of Windows 11
See https://www.windowscentral.com/software-apps/windows-11/how-to-enable-or-disable-fast-startup-on-windows-11

When that is done, be sure to do ( from Start menu) one Power >> Shutdown >> Restart.
Having "fast startup" can complicate our efforts to fix problems.

( 3 )

Please run the following custom script. Read all of this before you start. Please Close all open work.

Once the script-run has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program :  is FRSTENGLISH.exe which is already on Downloads

Please download the attached fixlist.txt file and save it to C:\Users\Raf\Downloads

Fixlist.txt < - - -

NOTE. It's important that both files, FRSTENGLISH, and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone.

Use File Explorer to go to the Downloads folder

RIGHT-Click on   FRSTENGLISH and select

RUN as Administrator

and reply YES to allow it to go forward to start.

That is important so that this run has Elevated Administrator rights !!

NEXT press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Downloads folder (Fixlog.txt) . Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.  It will reset the Winsock. It will attempt to clear all Cache and history on web browsers. Depending on the speed of your computer this fix may take 45-50 minutes or more. The main goal is to remove remaining traces of the autoconfig hijacker.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. 

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera + Brave caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Discord cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run. Attach FIXLOG.txt with next reply.

Windows Resource Protection found corrupt files and successfully repaired them.
Further, this run has removed unwanted exclusions that had been set onto Microsoft Defender.

I do expect that the JS Stealer pest is now gone.

Temporarily disable Microsoft SmartScreen to download the next software below 

I would recommend getting a readout report as to update status of some key apps.
Download SecurityCheck by glax24 from here

and save the tool on the desktop.

                   If Windows's  SmartScreen block that with a message-window, then
                         Click on the MORE INFO spot and over-ride that and allow it to proceed.

                             This tool is safe.   Smartscreen is overly sensitive.

Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"   and reply YES to allow to run & go forward
Wait for the scan to finish. It will open in a text file named SecurityType.txt. Close the file.  Attach it with your next reply.
You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

When all done, you may go back to turn ON the EDGE Smartscreen protection.

We can wrap up this case.
Let's go ahead and do some clean-up work and remove the tools and logs we've run.
Please download KpRm by kernel-panik and save it to your desktop.

  • right-click kprm_(version).exe and select Run as Administrator.
  • Read and accept the disclaimer.
  • When the tool opens, ensure all boxes under Actions are checked.
  • Under Delete Quarantines select Delete Now, then click Run.
  • Once complete, click OK.
  • A log will open in Notepad titled kprm-(date).txt.
  • You may attach that file to your next reply. (not compulsory)

Delete mb-support-1.8.7.918.exe
Delete mbst-grab-results.zip on the Desktop.

I am marking this case for closure.
I wish you all the best. Stay safe.
Sincerely.

Maurice
