How can I make my software not open source antivirus?

I am new to programming. I made a program from C # that controls a window. It includes a keylogger, file system and snapshot for screen functionality. I used the system tray notification icon to show and hide it. I made a choice in setting on startup in the registry. When I start the program, it is identified by Kaspersky as a virus and removed. I wanted to sell this program, but I don't know how to solve this problem. Is there a special certificate we can buy from microsoft or anywhere to consider the stroller safe? And what is this certificate called? Thanks to
