literally ESET NOD32 is the most fucking anoying AV to deal with, Im not going to lie it does not make a difference on the crypter, 5-15-20$, ESET Endpoint is one of the most advanced antivirus i know that is easily available. I have a paid version on my work laptop and can say that it very good at detecting anything dodgy, If not instantly, It will once it checks what any sort of file is doing and feeds it to workers of eset and they can analyse and write a signature for it. Thats if the program itself doesn't figure it out...
Dont worry i dont build bins on my laptop :P
