Ultimately the only thing that would protect the PC is a phyiscal security token. I use one at work - its based on OTP (one time pad - look it up on wikipedia) - the only way my computer account at work can be defeated is if a) they have my account pin (which a key logger can get) and b) they have the one time readout from my token (which is impossible to get unless my token is stolen - not likely).Every time I log in the password is completely different. So even if I had a keylogger on my machine - there's no way they could gain access - because at most they'd have my pin, but not the physical token.
