Hi Ian,

Thanks for posting your query on Microsoft Community.

This issue might occur if you have set any task scheduler for Windows Defender.

I suggest you to delete the task for Windows defender and check if it helps.

Follow the below steps:

• 
  Search and open Schedule tasks.
  
• 
  In the left-hand menu, open the Task Scheduler Library, then select
  Microsoft >Windows >Windows Defender.
  
• 
  Double-click Windows Defender Scheduled Scan.
  
• 
  Select the Triggers panel, then select Delete.
  

Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

 

how to reinstall windows defender?

The system is infected by miners and other malware, which have deleted your Defender executables completely. A repair installation is suggested.

Before that, please do the following:

• Download FixList.txt
  

• Save Fixlist.txt in the same folder where EnglishFRST64.exe is.
  
• Close all program windows.
  

• Launch the Farbar Scanner tool and click "Fix".
  
• Upload the output log file (FixLog.txt) to your OneDrive.
  

Once done, repair Windows 10. See How to perform an In-place Upgrade with Windows 10 Step-by-Step Guide - Microsoft Community:
