So I created a jpackage installer, but there are two problems:

-The browser detects it as a virus, when a user downloads it, (picture here )

-Operating system detects it as a virus either, and shows me a smartscreen protection screen.

How can I get rid of this two things?

Is there an offical guide to do it?

I read about signing the installer, but I got confused with that. And is that what is causing the problem?

Thanks for help!
