I'm off to grab lunch so I'll review more later but the project looks great. There's some additional feedback I have on reducing (or adjusting) AV detections and some personal knowledge having used AutoIt for about a decade now.
README
Unfortunately, you can't use AutoIt3.exe to execute an AutoIt script with includes in it since the included files won't exist on systems without AutoIt installed.
This is incorrect. Check out the Au3Stripper utility included in SciTE4Autoit. The output _stripped.au3 file should be executable without needing to compile to .a3x
ClipboardMonitor.au3
Swap to _ClipBoard_IsFormatAvailable / _ClipBoard_GetDataEx as this shows AutoIt can grab more than just text from the clipboard
Kelogger.au3
_IsPressed is intentionally nerfed. It works okay, but is not the best implementation. I have an example SOMEWHERE that I can send you privately
