Windows Defender Not On

Hi,



Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.



I would suggest you to try the below methods and check:

Method 1:

I would suggest you to run virus scan to make sure the computer is free from virus.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove virus, spyware, and other malicious software. It works with your existing antivirus software.

Microsoft Safety Scanner Download - Windows security



Method 2:

Turn the Defender on. Follow the below steps:

• In search, type Defender.
• Now make the option ON by moving the slider accordingly.

Method 3: Run the SFC.

Follow the below steps:

• Open Command Prompt.

• Select “Run as Administrator”.
• Type “sfc /scannow” without quotes and hit
  Enter.

Now check for the issue.



Keep us posted if you face any issues on windows in future. We will be glad to help you.

 

windows defender runs slow

Hi Thomas,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently. Let me help you in resolving the issue.

I would appreciate if you can provide us the following information to help us understand the issue better.

• Have you installed any third party security application in your system, apart from Windows 10?
  
• What is the make and model of your computer?

I would like to inform you that this issue might occur, if the Windows defender is scanning too many junk or malware effected files in the system. As of now,
I suggest you to run System maintenance task and check if it helps.

The Run maintenance task checks issues that might slow down your computer's, such as how many users are currently logged on to the computer and whether multiple programs are running at the same time.

Follow the below steps.

• 
  Press Windows + X on the keyboard.
  
• 
  Select Control Panel.
  
• 
  Select Troubleshooting.
  
• 
  Click on Run maintenance task under
  System and Security.
