Last year, in order to combat a particularly insidious virus known as DroidDream, Google remotely deleted infected applications from thousands of Android devices. Apps that appeared legitimate were bundled with malware, then distributed via Google’s Android Marketplace. More than 50 infected Android apps were detected and removed. Since then, all app stores have reported infections or leaky applications.
Google recently released a service called “Bouncer” that analyzes apps on the Android Marketplace for known malware, spyware and Trojans, with the intent to protect users before they download a malicious app. Not only does this service analyze new apps that are uploaded to the marketplace, but also existing apps.
In addition, Google has its remote removal capability, which lets them remotely remove a malicious app from your smartphone or tablet. This app removal feature is one of many security controls the Android team can use to help protect users from malicious applications.
