Alright, someone, please help....

My fellow co-worker is running Windows 98 and all of a sudden, as she was typing in Word, I noticed she began to type odd, random characters. I turned around, and she was like, "What's going on?!" When you hit any letter, for example, if you hit "g" it displays "g4321" and if you hit "q" it displays "q1" and so on and so forth. There isn't any definite pattern, as far as I can tell, and also, when you hit enter, it acts like it is the alt key.

And her mouse works fine....the computer runs fine, except for these odd keyboard happenings.

UPDATE I just checked again, while typing in notepad, if you hit the enter key on the number pad, it spits out "09874321" and if you hit the period key on the number pad, it spits out ".09."

So, I am stumped. She is scanning for virii but I don't think it has anything to do with that, but what do I know. Can anyone shine a light as to what is going on?

Thanks in advance.
