Windows SmartScreen’s purpose is to “screen” every single application you try to install from the Internet in order to inform you whether it’s safe to proceed with installing it or not. There are a few serious problems here. The big problem is that Windows 8 is configured to immediately tell Microsoft about every app you download and install. This problem can however get even more serious: It may be possible to intercept SmartScreen’s communications to Microsoft and thus learn about every single application downloaded and installed by a target."
