We’ve reviewed your submission and we've confirmed that the submitted files are clean. Windows Defender Antivirus doesn't report them as malware.
The message you observed is a notification from Windows Defender SmartScreen indicating that the application does not have known reputation in our system. Application reputation warnings are meant to inform end users when applications do not have known positive reputation. This doesn’t mean that the application is malicious, only that it is “unknown”. Please note that users can still proceed to download and run the application.
In most cases, a digitally signed application will establish reputation organically, unless something has happened to denigrate existing reputation such as being used to sign malware. We will investigate this issue further and contact you if we need additional information.
