Keyboard Virus?

The good news is, this is not on my PC or my brother's.

Just last night, my parents' PC suddenly had a strange behavior with the keyboard. Pressing any of the keys at the far left side (1, Q, A, Z, Tab) will make the PC tower beep, and then all other keys having the same line as the pressed key will respond.

Also, each problem key has some other responses other than the mentioned. Tested with Notepad, pressing A also brings up Winamp, Ctrl+F, and IE. Pressing Z erases an entire line of text. Pressing Tab shuts down the computer. Still so many others I cannot mention them all.

Tried updating the antivirus and running a full scan, no luck. Haven't tried more complex method yet, though.

Additional info: My parents' PC is old. It's still Windows XP, and the keyboard is still the purple plug (PS2)

Were you able to test another PS/2 keyboard, and if so, does it produce the same results? You may also want to try out a USB keyboard as well.

Maybe the keyboard is shot and is dying. Can you find a replacement keyboard and try using that?

It's been about a week or so since you reported this issue.

Did you try troubleshooting with our suggestions, Sandy?

I haven't had any chance. Been kinda... busy.
