    I'd vote for the filter key option in accessibility options as already suggested - i have played around with key loggers (for educational purposes) and in my experience they run pretty much indetectable to most people - certainly no drain on the cpu.

    it is a specific accessibilty option that is designed to only accept the key if pressed down a period of time for disabled users or people who may be a little clumsy on the keyboard - more like;y that i'd say than something sinister.

    Any techs, sys/admins or sys/engs out there come across a similar problem. If not I’m just looking for someone either to say “yes – that’s probably the cause of the problem” or “have you considered this instead”
    You've tried USB and PS/2 keyboards. There is NO common hardware there - it is a software issue. My vote goes to a trojan keylogger too.

    A way you MIGHT catch it is by bringing up task manager, keep it sorted by CPU percent. Then hit some keys and see if any processes seem to get real busy - if something gets busy, do a google on it and make sure its legit. If not, try killing it and see what happens.

    Download http://www.microsoft.com/technet/sys...sExplorer.mspx

    It displays the company name - and allows you verify signatures on executables. I have caught one virus that declared itself to be 'mircrosoft' but the spelling was inconsistent and no verifiable signature with it.

    It does seem like a keylogger, check what's running.

    And the other thing you can check is is it only affecting this user - ie if you log on as Admin on the machine, do you get the same issue?

    To be honest, no. I've overlooked that. Thanks. will get back to you on that one.
