This policy setting allows you to configure process scanning when real-time protection is turned on. This helps to catch malware which could start when real-time protection is turned off. If you enable or do not configure this setting a process scan will be initiated when real-time protection is turned on. If you disable this setting a process scan will not be initiated when real-time protection is turned on.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Windows Defender Antivirus -> Real-time Protection -> Turn on process scanning whenever real-time protection is enabled to ‘Enabled’ or ‘Not Configured’.
