Windows 10: how do i turn on windows defender antivirus

I cant turn on windows defender antivirus

:)

 

Windows Defender of Windows 10 stoped working and is not turning on

Hello NasirMahmood1,

Thank you for writing to Microsoft Community forum.

Have you installed any third party anti-virus software?

Step 1: Turn Windows Defender Service On.

Initially, we need to check with the status of
Windows Defender Service which might be stopping the defender to turn on.

• Press Windows key + R and type
  services.msc and press Enter key.
  
• Search for Windows Defender Service and check if it has been started.
  
• Right click on Windows Defender Service and click on
  Restart.
  

Step 2: Turn On Windows Defender Antivirus using Group Policy.

As you are on Windows 10 Pro build, I would suggest
gpedit.msc settings from the following link and set it to Disabled or not configured to
turn on real time protection setting. Follow the steps mentioned under
Disable real-time protection from the article-
Enable and configure antivirus always-on protection and monitoring.

Hope it helps.

Regards,

Defender AntiVirus

There are 4 options under Defender. Two refer to AntiVirus; AntiVirus Network Inspection Service & AntiVirus Services. Under Startup Type these two are listed as manual and the Status column said Inspection Service is running. When I clicked on the Start
button in Properties, I got an immediate message: "Win.. Def.. Anti.. Serv.. on local comp.. started and then stopped. Some services stop automatically if they are not in use by other services or programs."

 

Windows Defender Antivirus can't be turned on

So none of my suggestions in your first thread helped? Existing antivirus blocking Windows AV from updating. How to find the existing AV program?
What program was listed when you went to Security and Maintenance, looked in 'Security' and under Virus Protection?



How about the suggestions in your second thread? Can't turn on windows defender anti virus



And since you have three threads on the same topic a moderator may
