I have Real-time Protection on. Will it be running in background when I Close
Defender? Or do I have to minimize Defender? (There's no system tray icon
indicating whether it's running or not). Thank you.
 
Hello John,

If you select the Process tab you should see MSASCui.exe (the user
interface), and MsMpEng.exe (the service executable) running.
In Windows Defender--real-time protection is done by a system service,
starting at boot time--that's the Windows Defender service, whose executable
is MsMpEng.exe.
MpCmdRun.exe monitors for the existence of new signatures and is responsible
initiating the updating process when new signatures are available. ...check
that MsMpEng.exe within C:\Program Files \Windows Defender has permission to
run (firewall rule).
