❓ Undetected by antivirus?

Hey, I am William. I am gonna generally screw with some of my friends with a RAT. I have made it with Poison Ivy, but how do I get it undetected by anti virus like AVG and F-Secure. I would love to do this, it would get me 1 step higher in my achieve list.

Thanks in forehand.
