[Need] Every keyboard movement spy

I need a programm for an USB-Stick or an product which is able to do this, whch records every single letter or number which is written by the person on the computer.

Example: I have my USB-Stick with the programm on it, I go to the PC from my girlfriend and after 24hours I will have every single dot and letter on the USB-Stick which she have written to anybody on her PC.

Possible?

If you have the money something like this would be perfect for you as long as she isn't using a laptop: https://www.keelog.com

Otherwise most keyloggers are detected by antivirus, but if you have access to her pc you could add it as an exception to her antivirus. In that case just google around for a keylogger

Use njrat/nanocore and exterbyte encrypt the stub, tested with virustotal, only 1 Av returns error. (If you exterbyte encrypt njrat's stub, u cannot remotely uninstall it, which means u have to factory reset the computer.)
