I just stumbled across this lately, it’s a piece of software you install that should insert itself as a driver between the keyboard and the OS and encrypt all keystrokes – the idea would be that it would foil keyloggers.

An interesting concept, however I’m not fully convinced – I guess that I don’t fully understand how this works – but I tried installing it on a test machine and it did no harm – so I guess it won’t do any harm installing it.  There is a free version that works with IE and other popular browsers – to make it work with everything you need the pro (payed) version – IE is fine but just how do you test a product like this?  Install a keylogger yourself *lol* well let’s see…

a couple more detailed reviews here (although they did also omit installing a keylogger to test the software ;-));
