One of the concerns regarding the android approach to apps is that it is poorly policed and the more open approach increases the danger of malware infecting an android device. Google has responded to such concerns by creating software that attempts to identify malware in the marketplace – see this Google blog post. Google will even respond to the identification of a problem by remotely removing defective software from your device. Leo always says that removing stuff after equipment has been infected cannot assure protection. I wonder if “sand boxed” software eliminates this concern?
