There's a problem with real time scanning, macOS Catalina 10.15
F-secure says "Your computer is not protected, there is a problem with real time scanning, browsing protection is active". My subscription is valid.
F-secure has full disk access.
In the F-secure preferences pane there is a check box to allow real time scanning to move threats to trash. This is not checked. When the preference pane is unlocked, the box can be ticked but it doesn't stay ticked.
How do I enable real time scanning?
