Trojan Android App Bullies Google Play Users Into Giving It 5 Stars

Users who download "Music Mania" get pounded by ads until they say uncle.

IT security company ESET has spotted an ad-displaying Trojan mobile app on Google Play which is tricking users into give it five stars in exchange for a false promise of ceasing the app's aggressive flood of ads, reports ZDNet.
