Do scammers use AV? Which ones are commonly used?

Do scammers use Antivirus, and which ones do they commonly use? Is windows defender usually active or disabled?

I guess what I really would like to know is … I have a detected RAT but I don’t yet have a FUD crypter. What are the chances of being able to RAT them with a detected bin? Probably nothing if defender is enabled I guess.

I would just give it a go but I don’t really want to go through effort of spreading a bin unnecessarily if it won’t work.
