Ad Network Detector is a free program that scans Android devices for apps that use any of 35 different ad networks. It tells users what kinds of ads will be displayed and what user information those networks collect. The program is a response to the rise in very aggressive behavior by ad networks that some developers rely on to make money on their for-free Android software. Lookout butted heads with Symantec when the latter initially called out 13 apps in the Android Market as malicious. The app can be downloaded free of charge from Google’s Android Market.”]
