Zemana Antilogger is pretty sufficient for these threats, and also blacklisted by the NSA, so I suppose it works then? I wrote some custom apps that use 'key-interleaving' so that as I type, the key is backspaced, replaced by another letter, and then substituted several times. It's trivial to write such an app, and takes about two-days. The hardware keyloggers are much more insidious though and that keyboard advertised on the site looks awesome :)
