Beware of Android FREE Apps

Android platform is an open source platform to develop applications. From Android Market you can get plenty of free apps for your android smartphone. Recently I downloaded a free game from android market which was developed by a very good company, I played this game and I liked it. The game is awesome but after 2 days I faced problem while connecting my device to my pc, my smartphone was unable to detect that it has been connected to pc???
Now after searching for problem I found that the most latest change I did in my phone was installing this app(game) from a very good company...
