They all point blame at KbdF.sys
which is some 3rd-party keyboard filter driver.
To be honest, I'm very concerned about this. Googling shows up absolutely zilch on this driver and what application or hardware it's for, and whatever does come up is in people's viral scans complaining it's a keylogger. Unless you can explain to me why you would expect some 3rd-party keyboard driver is present on your PC, we can assume this is the result of an infection.
You may wanna mosey on over to this
forum and post a thread there, directing them to this thread under suspicion that your computer may be infected.
