Windows 10: Hi my windows defender wont let me run a scan or even open and is blocked by a error...

when i try to run a scan windows gives me a error pop up and tells me to contact itthis is my home computer. However my windows defender policy manager has only the default file but the default file data is set to "not set yet" idk what that means. When i double click it tho the string is empty. Idk if that is the problem but just thought i should include that. I'm not well versed with windows so idk what other info would be needed to know why its not working.

defender scans

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.
