Suspicious application and setup file

Avast Free Antivirus / Premium Security
1

Good Morning.
I have recently developed an application using C # and visual Studio 2017.
When i execute the application, the Avast scan appears because it detects it as suspicious. At the moment it says that it does not have a virus and the program runs correctly.
On the other hand, I have also generated a setup file using Inno Setup. When I run it, the Avast scan jumps several times in the installation process, which is generating rejection among my clients.

Please, I need help to fix it …

Thank you very much in advance.

Good morning.
The software meets all the points of the posts. The only possible conflicts that occur to me are:

Landing page:
    I've not web page. The software cannot be download. It's installed "in situ" by the seller.
Signing software:
    I've signed for testing and the result is the same.
