The EV Code Signing process can provide reputation service within browsers, operating systems, and security software an additional source of confidence in applications signed with EV Code Signing certificates. Symantec has partnered with Microsoft to integrate EV Code Signing certificate status with their SmartScreen® reputation services in Internet Explorer and Windows®.
Programs signed by an EV Code Signing certificate can immediately establish reputation with SmartScreen reputation services even if no prior reputation exists for that file or publisher. This means there are potentially fewer warning messages when a user tries to run your application. It is also required for all new kernel and user mode drivers released on Windows 10 platform.
