I've been making crypters for roughly 2 years now, and the answer is that no major name brand AV will protect you, just go to a crypter sales thread on HF or even here and you'll see a list of AVs that are shit. I have yet to find a good AV that isn't business level and is either cracked or doesn't cost crazy money. I would personally recommend writing your own, its what I did for active memory scanning of processes, and it works well. I would recommend not being stupid, and just individually scanning on virustotal
