Is your SmartScreen Filter turned off? Or do you get the message SmartScreen Filter cannot check this website? If that is so, this post will show you how to enable or disable SmartScreen Filter on Windows 10/8/7 using the UI, Group Policy or Registry Editor.
For those who don’t know what SmartScreen is, it is a feature that helps detect phishing websites, and can also help protect you from installing malicious software or malware. So whenever you encounter a suspicious site, a warning will be displayed on the browser window to notify the user about the sites nature and whether user trusts the site owner/publisher to continue further on the URL provided.
