Our tests demonstrated adtronic to be a well behaving application that did exactly what it said it would.
The user interface was easy to locate, the instructions to set the minimum/maximum limits were clear, and the ads themselves weren't actually all that intrusive. Downloading the ad banners requires a data connection and that is clearly stated. It was also easy to uninstall when we were done testing.
Combined with a set of free applications that people really want, this could be a successful business model. Success interests us because a money making business model will be noticed by eCrime.
Advertising revenue is the target of many DNSChanger PC malware families.
Also, while there are still some good Windows based ad supported applications, there are many more that crossover into adware and spyware.
