The user Ciellix had a similar issue to this problem on this forum, but the solution to my problem may be different than his, so i'm reaching out for help on a new forum thread. I already went ahead and downloaded the Farbar Recovery Scan Tool as suggested in the other forum, and the appropriate documents are attached below.

 

Similar to Ciellix, my Windows Defender doesn't work after removing Mb. Please Help!

Hi @DarylDeakler 

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

Be very sure to Save any work-files you have open at this point. Close & Save any open edits, if any. Next, a custom script to do  checks & some  cleanups. This is really just housekkeping.

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

This custom script has some specific things, plus some general aspect to help the system overall.  Hoping it will not exceed 60 minutes in execute time.

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 rebuild the Winsock. 

NOTE-2: It should get MS Defender antivirus back to normal & it will attempt to get it updated & do a Quick scan.

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  & BRAVE 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          <<< - - - - -

Then, Start the Windows Explorer and then, go  to the Downloads   folder.


RIGHT click on FRSTENGLISH    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.

I cannot. It says, "Threat service has stopped. Restart it now." And then when I restart it, it tries to restart and then fails and comes up with the message, "Unexpected error. Sorry, we ran into a problem. Please try again."

One more thing, when I right click the Windows Security in the tray, and click on run quick scan, it comes with a pop up saying, "Page not available" "Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact IT helpdesk for more information."

Hello @DarylDeakler

While we await for @Maurice Naggar to return, please run the following which may help provide further information to assist him.

 

 

Please download the following tool

Farbar Service Scanner and run it on the computer with the issue
http://www.bleepingcomputer.com/download/farbar-service-scanner/dl/62/

 

Make sure the following options are checked:

  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center/Action Center
  • Windows Update
  • Windows Defender

Click "Scan"

It will create a log (FSS.txt) in the same directory the tool is run.
Please attach the log to your next reply.

Alright. Thanks for the status update. Be very sure to do a Microsoft Windows Update run.

There were Windows system events logged as recently as 13 April and March 4 about update failures via Microsoft Update about the Microsoft Defender engine and definitions.

I would highly suggest to re-insure that this pc is all up-to-date with security updates & cumulative upates on Windows. select the Windows Start  button, and then go to Settings  > Update & Security  > Windows Update . and click Check for Updates.
Have much patience.
