WINDOWS DEFENDER is turned off

Hi Ahmed,

Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

• Type Windows Defender in the Search bar and press
  Enter.
  
• Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
  

Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
