Google Play Protect is an always-on service on devices which said to scan 50 billion apps each day across a billion Android devices to ensure they are safe.
Google already has a number of security measures in place to help keep your smartphones safe, including Verify Apps and its Bouncer service, but once apps are uploaded to the Play Store and installed on your device, Google does not have anything in place to monitor the behavior of those apps – something that most malware apps were abusing.
Running automatically in the background, Google Play Protect is actually built into devices, which will not only analyse apps before appearing on the Play Store, but also monitor them once installed on the device, including apps that have been installed from third-party stores as well.
For this, Google makes use of machine learning algorithms that automatically compares app behavior and distinguishes those acting abnormally, and if encounters any malicious app, it warns you or even disables the app to prevent further harm.
Google says it works around the clock to keep up with the latest threats.
Google says the new machine learning system regularly updates to help Android ecosystem stay one step ahead of any potential threats by always looking out for “new risks, identifying potentially harmful apps and keeping them off your device or removing them.”
