US search giant Google will integrate a malware scanner in the Google Play application store to keep malicious apps from reaching users, a tech website says. Android Police reports there are two parts to the scanner: an \"App Check\" that inspects all of a device\'s applications already installed to determine whether any existing apps may harm the device, and a so-called \"doorman-style app blocker\" that warns a user if an app about to be downloaded is possible malicious or has been tagged as suspicious. Google is apparently reacting to a number of rogue apps showing up in the Android application store in recent weeks and months, ZDNet reported. The malware scanner may be based on a free online scanning utility developed by VirusTotal, which Google acquired last month, ZDNet said.
