Flappy Bird, developed by a 29-year-old, Dong Nguyen, was one of the top free gaming apps of the last month, but now officially unavailable for users. The app’s popularity will help them to gain success in spreading Smartphone malware to mass and hence, the malicious apps are available in play stores with undesirable side effects. The real version of the app was available for free and users began downloading it from their play stores, without bothering whether it’s the real version or not.
