Once started, logkeys works in the background, saving all the key strokes, even when AltGr or Caps Lock are used. Thus it won't be difficult to know what websites the user has visited or what they have been doing on the computer. That is why a malicious user would also be able to gather information about account names and passwords with ease with this kind of application.
The keyboard's interface doesn't matter at all, because logkeys works both with USB as well as PS2 keyboards, so no key strokes will be missed.
The main advantage of logkeys regarding other similar applications is its more advanced logging method when it comes to eliminating false double strokes and other similar keylogger errors.
