Weird keyboard problems / Possible keylogger?

[Fred]

One of my clients has a one year old pc that is running Windows Vista
SP1 on there. Recently she started complaining that her keyboard was
acting a little weird. It is intermittent but she will be typing and
letters will just not appear on the screen. Some delayed reaction as
well, but not that delayed.

The first thing I thought is that the keyboard was having some
physical issues. So not only did we try another keyboard that is
known to work we tried her keyboard on another computer. Needless to
say the other keyboard has the same problem on her computer and her
keyboard works just fine on a different computer. So I know it is not
related specifically to the keyboard. It is a USB keyboard and we
have tried different ports etc.

My concern is that the problem is a keystroke logger. I would be
really surprised if one was on there though. She doesn't really do
anything but read email on the computer. Do a little shopping
online. Her computer came up clean on spyware scans with at least
malwarebytes anti-malware. I didn't personally, but she does have the
latest ad-aware loaded and she claims that she has scanned with that
already. I haven't tried spybot yet either.

It is a hard problem to search for really and I think I have seen a
few issues relating to Vista updates. But nothing concrete that I
could find yet. I don't know what if any good keystroke logger
scanners are out there either. They all seem to be a joke. Any help
with this issue will be greatly appreciated!

Thanks,

Fred

I see this alot with XP when the user has inadvertently activated
"Filterkeys".

Do this:

Start, Control Panel, Ease of Access, Make the Keyboard Easier to Use. See
if "FilterKeys" is checked.
