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.

 

Setting the Scan Schedule in Defender

You can schedule your Full Scan by following the steps provided here:

How do I set Windows Defender to a custom auto scan

However, there’s currently an issue where scheduled scans will only run sporadically when they're running under the
System account – so when you get to step 7, don’t change the user account – leave it at its default (administrator).

Automatic Maintenance normally runs a daily Quick Scan, but since the Automatic Maintenance scan runs under the
System account by default, it’s also being affected by this same issue:

Scheduling Windows Defender scans

Hi Gary,



Thank you for writing to Microsoft Community Forums.



I understand your query related to Scheduling Windows Defender Scan using Task Scheduler.



Ideally, when you schedule a task using Task Scheduler it should run during the time. However, if the PC was not switched on at that particular interval then the scan might have taken place.



You can try enabling the History of tasks in Task Scheduler to check more information.

1. Press Windows key + R. This will open
   Run. Alternatively, you can go to Start and search for Run.
   
2. In Run dialog box, type taskschd.mscand hit
   Enter.
   
3. Now right click on the Action tab
   
4. Select Enable All Tasks History
   

You may also want to try changing the settings of the task that you have scheduled.

1. Press Windows key + R. This will open
   Run. Alternatively, you can go to Start and search for Run.
   
2. In Run dialog box, type taskschd.mscand hit
   Enter.
   
3. Double click on the task that you have scheduled
   
4. Under General tab, change the settings for
   when the task should run.
   
5. Now under Settings tab adjust the settings
   as per your compatibility.
