You can try adding the url to the trusted sites and turn of Smartscreen for that zone, but I would not recommend that.


You can report a false positive:

From the warning, you can choose to report this site as a safe site. Click the link for More information then click Report that this site does not contain threats. Follow the instructions on the feedback site to complete this process.


You can setup Smartscreen so that users can bypass. 


Hope that helps!



Will try this thanks
