Google announced today that it’s teaming up with three security companies to help identify malicious apps before they’re published on the Play Store and can potentially do harm to Android users. The company is calling this partnership the App Defense Alliance.

Google already builds Google Play Protect, its malware protection service, right into Android. The company says it also uses Play Protect to scan “billions” of apps every day on the Play Store. So it seems like Google should already be catching these bad HUC99 apps — but apparently, the problem is big enough that the company felt the need to bring in some reinforcements. In theory, with more companies helping scan Play Store apps, there’s a better chance you won’t accidentally download one of the bad offenders on your Android device.
