Disabling (Self Defense ) / Nod32 / With an script

[dyn!o]

If you mean accessing the control then you can do it by enumerating its attributes and sending window message. I guess you do not mean that.

If you mean accessing the code responsible for the behaviour of this setting then the news are not good for you: there is no interface (pipe).

The question is a bit strange. Even if you would somehow manage it then it is an awful way of avoiding the detection.

I would search for some allowed trick instead. The more officiall trick, the lower probability it gets detected. Nowadays anti-virus has to allow many precious APIs used by legal software. Learn them and use them.

A long journey for you... but then... you can make your keylogger done.
