Windows Defender - This app is tuned off by group policy


Hi everyone!
I'm italian, my english is not that good and I'm new on this forum.
My PC was infected by malware but now I think I solve it.
The problem is Windows Defender.
If I try to open it, came out this message:
"This app is turned off by group policy - To allow this app to run, contact your security administrator to enable the program via group policy"
I tried to open Local Group Policy settings but there isn't Windows Defender folder (Local computer policy - Computer configuratio - Administrative templates - Windows components).
In Services - Windows Defender Services I found:
"Startup type: Manual" and I can't change it.
"Service status: Stopped".

Does anyone have any advices?
Thanks

 

Windows Defender Group Policy Disabeled

Hi,

Thank you for contacting Microsoft community.

I would like to suggest few troubleshooting steps:

Method 1: Disable group policy from gpedit.msc

• 
  Press Windows key + R.
  
• 
  Type gpedit.msc and click Ok.(it will open Local Group policy editor)
  
• 
  Go to Computer Configuration/Administrative Templates/Windows Components/Windows Defender.
  
• 
  In the right pane of
  Windows Defender in Local Group Policy Editor, double click/tap on the
  Turn off Windows Defender policy to edit it.
  
• 
  Select (dot) Not Configured or
  Disabled, click/tap on OK,
  
• 
  When finished, you can close the Local Group Policy Editor if you like.
  

If the issue still persist you can follow method 2.
