1.) How Smart Screen works!

The functionality of Smartscreen is relatively extensive, but there are some basic points that are easy to understand.

There are so-called unknown applications and known threatening applications . These are displayed by SmartScreen with the relevant message.


Known threatening applications
If a warning message appears when starting an application that is entered or noted as malware in the Smartscreen database, a message appears that the software or the corresponding application is threatening. 


Warning message for unknown applications
If the application is something that is not stored in the SmartScreen database, a warning message will be displayed stating that Windows has prevented the start of an unrecognized application. You can bypass this message at your own risk if you are sure that the software, application, program, etc. is safe.

Watching for warnings in the browser is also important, here you will see a virus-infected download that is automatically displayed in the browser. This is password-cracking software that decrypts passwords and is therefore classified as a virus.

2.) Warning when running an unrecognized application!

Of course, Windows Smart Screen does not recognize all software, especially software that is rarely downloaded from the Internet, which will automatically be classified as an unrecognized application. But it is also true that the security measures are set quite high and are intended to protect you from malware and other threatening programs.

It is also true that you will rarely need your seatbelt in the car, but it still gives you a good feeling of security when you do wear it.

Smart Screen warning message

Here is an example of a warning message if your computer has been protected by Smart Screen, usually these are older applications or applications without a manufacturer's name, or where there is no certificate for the respective software.

For this ►►  EV and OV Code Signing?

If you are familiar with the manufacturer or the source from which you downloaded the file, you can click on "more information" and you will see the manufacturer if applicable. For unsigned software, it says "unknown". If you trust the software you have downloaded, you can click on "Run anyway" to start the program.
