Everytime anyone tries to download my application it shows virus detected and need to press special option to keeps the game
This is the antivirus throwing a false alarm. There is not much you can do I’m afraid. Antivirus programs try to be very strict. It’s better to label a safe program as dangerous (and let the user decide), than not label a dangerous program as such and let it run on the machine.
There are a few options, like signing your program for windows, but that costs money. If interested you can probably search online for more information.
