The MS Windows SmartScreen filter (appeared in Internet Explorer 8 first, then implemented into the MS Windows OS starting with Windows 8.0) may be a useful security feature in some scenarios that will help prevent bad applications from running, but in most (!) cases it may prevent a legitimate application from running. SmartScreen reports many information to Microsoft, so it does have privacy implications!
Therefore we recomand experienced users to turn it off.
