How do I make installed antiviruses detect a program?

Question

I'm trying to make a program that gets detected by almost all antiviruses, but the program shouldn't do anything to the computer. I am attempting to get a trogan/rat/worm false positive, but if I put rats I made into the system, it doesn't alert the AV. I know they detect on a list and not on the fly, can I change the programs fingerprint to one that is commonly used as a virus?

How do I make anti-viruses detect a false positive?

Answer 2

So I tried to make an PUP(Potentially Unwanted Program) and was successful too. It was flagged by windows defender What I did was make a python script which will automatically run in background, download a Video, and then it changes the program's Directory too..
