Where your device will be protected or protected from viruses. For that, please refer to the review of turning on Windows Defender below.

Why Can’t Windows Defender Real-Time Protection Be Active?

If you feel that the method above doesn’t work, there may be a problem where you install a third-party antivirus. This third-party antivirus can prevent Windows Defender from running.

If you think you have installed it, please uninstall it first so you can turn on Windows Defender.

If you install an antivirus such as Avast, Smadav, and so on, please turn it off first for the process of turning on the Defender.
