Windows 10: Computer says Defender is off?

Recently I received a message from my computer that said Windows Defender needed to be turned on. I checked, and it was already on. Why did my PC do this? (I have Windows 8)

Windows Defender automatically disabled

Hi Ahmad,

Thank you for responding.

I suggest you to place the computer in safe mode and check if the Windows Defender works.

Method 1:

Step 1: Start computer in safe mode.

• 
  Type Settings in the search box on the desktop, select
  Settings.
  
• 
  Here select Change pc settings and then
  General.
  
• 
  Scroll down to Advanced startup, click
  Restart now.
  
• 
  Click on Troubleshoot, Advanced options, and Startup Settings.
  
• 
  Click Restart, select
  Safe mode and then press Enter.
  

Step 2: Try to
run the Windows Defender in safe mode.

Steps:

• Press Windows key and type Windows Defender.
• Right click on it and select Run as Administrator.
• It may prompts you to enter the password.

Method 2: If the issue still persists, place the computer in normal mode and check for the Windows Defender services.

Step 1: Place the computer in normal mode.

• Press Windows + R keys to open
  Run command.
• Type msconfig and press
  Enter.
• In the System Configuration
  window, click on General tab.
• Select Start-up selection as Normal startup, click on Apply and Ok.
• Follow onscreen instructions.

Step 2: Once you are in normal mode, I suggest you to check for the
Windows Defender services.

• Press Windows + R keys to open
  Run command.
• Type services.msc and press
  Enter.
• Search for Windows Defender, right click on it and
  start the service.
• Also, set the Startup type to
  Automatic.
• Do the same for Windows Defender Network Inspection Service.
• Now check if you are able to access Windows Defender.

Hope it helps. Kindly update the status of this issue, we will be happy to help you.

 

Cannot activate Windows Defender

On my laptop "Toshiba Satellite L455" I did upgradation to W-10 from W-7 (original).

There is no antivirus program on this PC.

I wanted Windows Defender to run. But it says that it is switched off.

Want to activate it.

On opening Windows defender, there is no option to activate it.

In step 2 of your suggestion, it says:

"Windows could not start the Windows Defender Network Inspection Service on local computer.

Error 1068: The dependency service or group failed to start"

Can you pl give a method to activate the defender?
