Earlier quoted context omitted.
I'll cut you some slack because you stated you're not a malware developer. But even if you're a normal developer, you should know that telling software to do something does not mean that the software will do that something. When the software in question is subject to being controlled by adversaries, all guarantees go out of the window.
Yeah. I facepalmed at that assumption as well. It's as naive as a parent telling an 18 year old not to have friends over while they go on vacation for 2 weeks and thinking its all good from there.
You can go as far as finding the amount of data software is sending over the wire through the Task Manager -> Performance -> Resource Monitor. And to say an AntiVirus can hide this would mean it shouldn't be trusted whatsoever if it behaves like malware. The type of reputation any sane A/V company does not want to fall under.
