Google Android 4.2 - Will offer Application malware scanning service
Google will offer a new malware scanning service that can help identify malicious applications as documented below.
QUOTE: Users with Android 4.2 (Jelly Bean) devices will have the option of scanning apps installed on their devices to identify malicious apps, Google engineer Michael Morrissey wrote in a Google+ post on Wednesday. The new mechanism would complement the existing Bouncer technology, which scans apps as they are uploaded to Google Play to detect and remove malicious apps, by scanning apps as they are installed on the device.
"We will check for potentially harmful applications no matter where you are installing them from," wrote Morrissey, a member of the Android Security team. Google has already begun rolling out this feature to Nexus 7 and Galaxy Nexus devices as an over-the-air Jelly Bean 4.2 update. The app verifier is enabled by default, according to a Web page describing the security settings in the Nexus 4.
