SmartScreen: a reputation based filter
Windows protected your PC
Windows SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.

The message may be shown by SmartScreen, a Microsoft filter to protect your PC from harmful applications.

To install SmartHanzi, click  Learn more  Run anyway  and proceed as usual.


SmartHanzi is signed with a standard Code Signing Certificate from Sectigo which guarantees the integrity of the downloaded software.

As explained in this tutorial, a standard certificate also helps gaining reputation:

A more expensive EV (Extended Validation) certificate would be needed to completely avoid the SmartScreen message.

Use  Microsoft Edge  to download the application

The download link in SmartHanzi home page (when a new version is notified) now directly opens Microsoft Edge.

It was previously recommended to try Firefox in case of difficulty with IE. This made sense at the very beginning when SmartScreen was a part of IE. With SmartScreen a part of Windows, it is strongly recommended to use Microsoft Edge and improve reputation.

It is in no way recommended to turn SmartScreen off. See SmartScreen FAQ for more details.
