Copy/Paste spy loggers

it always depends on where u are and what kind of system.
a keylogger is not a clipboard logger.
for windows i didnt see a keylogger since 3 release of windows ago, but for linux
its not so difficult to patch the kernel that every key hit on the keyboard is logged in ascii in a txt file.
but when u use c&p first u dont use the hardware keys, and second, when u use windows he dont save the copied information, like (k)glipper for example in linux.

most important and very dangerous, much more than what u say it passwort saving in the firefox in netcafe
Noobs which dont understand much about pc klick "password saving" in netcafe. and many netcafe dont erase the personal data after a login session.
so i already very open saw very many passwords saved in firefox.
this people dont understand about privacy and passwords. in netcafe passwort saving option should be disabled.

ontopic:
i think c&p is quite save, even he "forgot" the password after 10 sec.

solution for extremly paranoia variation :

u make the password readable, than u change it a littlebit, copy it in the asteriks-box and change it there again.

then no keylogger or c&p logger can logg anything right
