Hello @dadawg

My name is Maurice.  I will guide you.  Please only just stick to "this" topic thread.   ( not the first one you had hopped on)

I will be providing custom guidance.

[  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.

[  2  ]

We will use FRSTENGLISH.exe  on  Downloads    folder to run a custom script.    The system will be rebooted after the script has run.

This custom script is for  dadawg  only / for this machine only.

This custom script has some specific things, plus some general aspect to help the system overall.

NOTE-1:  This script will  run a scan using System File Checker to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.  It will also run the Windows 10 DISM to check the system integruty. 

NOTE-2:  It will attempt to remove the oldest volume shadow copy.

NOTE-3: 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 caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player 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.

Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this.

 
If there are any CD / DVD / or USB-flash-thumb or USB-storage drives attached,  please disconnect any of those.

Please save the (attached file named) FIXLIST.txt   to the  Downloads  folder   

Fixlist.txt


Start the Windows Explorer and then, to the Downloads  folder


RIGHT click on  FRSTENGLISH.exe    and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
IF Windows prompts you about running this, select YES to allow it to proceed.

IF you get a block message from Windows about this tool......
click line More info information on that screen
and click button Run anyway on next screen.

on the FRST window:
Click the Fix button just once, and wait.

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. 
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your next reply later, at your next opportunity   


Please know this will do a Windows Restart.   Just let it run and finish.   I will look forward to getting the log.

Thanks. Overall a good run.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on Scan Options & select FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

  • 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.

 

Let me know the result of this.    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.

Excellent    

Results Summary:
----------------
No infection found.

And your most recent scan with Malwarebytes for Windows at  2021-12-03   your local time 20:04:30Z  reported no malware.

<

Additional suggestion.  Should not take a lot of time.

From the Start menu, select Settings, then select Update and Security.

Next, look at the left-side menu & select Windows Security

Next, In Windows Security section: Click on the grey button Open Windows Security

Now, click on the shield Virus and threat protection

On the next display, look at all the options.  Look down the list and see "Check for Updates" .

You should click on that to have the system check for updates for Microsoft Defender.  Watch & wait for that to complete.

Please also note that the Scan options (all) can be displayed by clicking on Scan options.
Do a QUICK scan.
Let me know the end result of what the Microsoft Defender reports.

Good.  I believe this system is good-to-go.

We can proceed with cleanup of tools we used.

To remove the FRSTENGLISH tool & its work files, do this. Go to your Downloads folder. Do a RIGHT-click on FRSTENGLISH.exe & select RENAME & then change it to

UNINSTALL.exe

.
Then run that ( double click on it) to begin the cleanup process.

Delete mb-support-1.8.n.nnn.exe
Delete mbst-grab-results.zip on the Desktop.

Delete msert.exe
Any other download file I had you download, you may delete.
Consider using PatchMyPC, keep all your software up-to-date - https://patchmypc.com/home-updater#download

Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

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

Maurice
