Windows Defender unable to turn On.

 

 

I recently had Avast antivirus installed. But removed it properly using Revo Uninstaller.

 

I ran Services.msc and found that Windows Defender is set to manual (but is unable to be set to automatic, location is greyed).

 

When I run Action Center, in order to Turn ON Windows Defender it simply opens Windows/System32.

 

Please help.

Perform the following troubleshooting methods:

Method 1:

I would suggest you to make the “Windows defender Service” startup type to “Automatic”.

Follow these steps:

a. Press “Windows key + R” from keyboard.

b. Type “services.msc” without quotes in the “Run” Window and hit enter.

c. Search for “Windows Defender Service”.

d. Make “Startup Type” to “Automatic”.

e. Restart the computer and then check how it works.

Method 2:

Perform System File Check (SFC), and then check if this fixes the issue.

Follow the steps:

a. Press “Windows Key + Q” to open Charms Bar.

b. Type “cmd” without quotes in the search box.

c. On the left pane, right click on the “cmd” option and select “Run as Administrator”.

d. Type ‘sfc /scannow’ without quotes and hit enter.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

Thank you Francis,

 

Method #1:

As I mentioned above, the section to adjust to 'automatic' is unadjustable. (Has been turned to grey).

 

Method #2:

Performing a search online, this was suggested in another post.

Completed just 10 minutes ago.

No errors were found.

 

 

Thank you for your responses.

Do you have any further suggestions?

Please do not suggest a "REFRESH" or "RESET".

 

Thanking you in advance,

Remove Avast with Avast Removal Tool

 

How to uninstall our software using aswClear:
  1. Download aswclear.exe on your desktop
  2. Start Windows in Safe Mode
  3. Open (execute) the uninstall utility
  4. If you installed avast! in a different folder than the default, browse for it. (Note: Be careful! The content of any folder you choose will be deleted!)
  5. Click REMOVE
  6. Restart your computer

Thank you Francis,

 

But when I try this, (and I have...do not take that rude)

a window / folder pops up and it is /windows/system32.

 

Anything else?

  1. Open Command prompt window in Run as Administrator
  2. In the command prompt, type net stop winmgmt then hit enter->type Y for the asked question and keep the window open
  3. Open Run Window and type wbem and hit OK
  4. You can see a folder with the name Repository, right click and rename it to Repository.OLD
  5. Close that window and type net start winmgmt in the command prompt again and hit enter
  6. Restart the computer once and check the Action center status

Francis,

 

Maybe I can ask you this because you know more than me.

 

Found the following while researching online,

 

Performing miscellaneous checks:

 * Windows Defender Disabled

   [HKLM\SOFTWARE\Microsoft\Windows Defender]
   "DisableAntiSpyware" = dword:00000001

 

Unable to set to '0', displays an error message..

  "Cannot edit DisableAntiSpyware"
