Antivirus deletes my deployed application

Hello!

I deployed my application to my website. However when I download the "setup.exe" from the website, Google Chrome starts warning me that the application could be risky to launch. Ignoring Chrome, when I launch the application and install it, I can not run it because Windows blocks the application from running because it is a potential risk for my computer.

My application does not contain any harmful codes. How do you guys fix this problem?
