Pff. Simple enough, build a server, crypt that server and send to the victim binded with another executable. When user downloads, have server run in background that allows for automatic download of your Keylogger/RAT/Stealer. When server shows RAT or Keylogger is done downloading have it place it somewhere on the C:/ and edit startup to boot the Keylogger/RAT/Stealer
More undetectable than sending the whole Keylogger/RAT/Stealer with the file as he can just delete the file you sent, unsuspecting anything and you are still game.
