You may have a virus or trojan or worm or adware or some other sort of malware. Run an AV scan, and download AdAware and Spybot, install them, update them, and run. Delete anything that looks suspicious. Some advise deleting everything because it's all reversible. Also get Spyblaster which keeps a list of bad stuff on your computer and blocks them from being installed (theoretically). Be sure your independent (not MS’s) firewall is enabled. Spybot AdAware

You might also go to Keyboard in Control Panel, to the troubleshooting section and see if that's any help.

If you have a newer keyboard, be sure the "F-Lock" function is enabled. You may or may not have this feature on your keyboard. It's in most newer Microsoft/Logitech keyboards, and keys have different functions when F-Lock is not engaged. Just a tip. What kind of keyboard is it?
