Window defender does not work after I uninstalled Malwarebytes

[NVDUNG]

I have uninstalled Malwarebytes using mb-support-1.8.7.918 but after that my window defender does not seem to be enabled.

When I tried to restart virus & threat protection the screen always stayed like this.

Hello @NVDUNG   

My name is Maurice. We will start with getting a couple of key reports to check a few bits of status information. 

This next is just a report to check on some Windows services  

Download   Farbar's Service Scanner utility

and Save to your Desktop.

Right-Click on fss.exe and select Run As Administrator.

Answer Yes to ok when prompted.

If your firewall then puts out a prompt, again, allow it to run.

Once FSS is on-screen, be sure the following items are check-marked:

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

  

Click on "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.   Please attach that file.

I would recommend getting a readout report as to update status of some key apps.

• Download SecurityCheck by glax24 from here  https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe

 

• 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

Stick with me.

Thank you Maurice but I've managed to fix it after I read an old thread. Here is the link:

It seems like I was missing some file on Window's security health service. After I reinstalled my OS everything was back to normal

Good morning. It seems situation is normal. Is there anything else ?

[Maurice Naggar]

Delete mb-support-1.8.n.nnn.exe
Delete mbst-grab-results.zip on the Desktop.  You no longer need that tool. 

What follows is just a tools cleanup. 

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)
