Google Play Protect scans all apps on users Android phones, even those downloaded from outside Play Store, for malicious activity and notifies users it finds something suspicious.

periodically scans your device. If it finds a potentially harmful app, it might:

Send you a notification. To remove the app you have been warned about, just tap the notification, then tap Uninstall. You can also disable the app until you uninstall it.
In some cases, if a harmful app has been detected, you may also get a notification saying that the app has been removed. It runs a safety check on apps from the Google Play Store before you download them.
