I'm not sure what they call it, but Windows does get in the way for things you compile on your own machine. I compiled the JuicyPotato exploit and tried to copy it to another local folder and got error 0x800700E1 and the EXE went missing.
That's Defender behavior -- you'll want to disable antivirus before building viruses :)
Defender is a traditional hueristic-based AV with on-disk and live load scanning and an offline database. SmartScreen is a reputation-based (certs + "how many people ran this") checker, and is much more visible. Win10 runs both.
