Earlier this year I/O 2017, Google announced that they had plans to bring enhanced device security to the Android ecosystem. They intended to prevent malicious apps on the PlayStore and they have now started rolling out the security suite on all Android smartphones running Google Play Services 11 or higher.
The new feature is automatically added to all Android devices meeting the requirements. One can access Play Protect on his/her Android smartphone by going to Settings> Google and then tap on Security. You will find Google Play Protect and you can view the apps that have been recently scanned. Users have the option to disable the feature by toggling the "scan device for security threats". You can also let the app send malicious apps on your device, if detected, to Google for clearing out the PlayStore.
While the feature may not sound to be anything special, it is a major step towards preventing malware attacks on the world’s most popular smartphone platform. Android has seen many recent malware attacks and Google’s decision to roll out security features for a million Android devices around the world will help it eradicate most of the malicious applications from the PlayStore.
