I've recently made the switch from an iPhone to a HTC Wildfire and although I'm very happy with the new phone and OS and I am a little concerned about the security of third-party app on Android devices. With my iPhone I knew I could safely download the Paddy Power sports betting app or the Bwin poker app because I knew they were tested by Apple to within an inch of their lives. Since getting my Droid I've had to enable apps from "Unknown Sources" which makes me a little anxious to begin with. I don't mind installing apps from well known brands like Betfair or Bet365 but there are also some casino apps that I'd like to try but I'm not sure if they're worth the risk. Has anyone here had any bad experiences in terms of viruses or trojans after installing apps from Third party sites?
