keyboard error?

I am using a very old laptop (Toshiba), the built in keyboard was spoiled and I took it out and now using a USB keyboard now. Also I am using a wireless adapter (USB). All of sudden, the key "r" repeatedly occured on the screen automatically when I was using MSN and there is no way to supress it.I pull out the external keyboard and found out it is still doing the "rrrrrrrrrrrr". I have the AVG antivirus installed and nothing found. Could any of you expert tell me what is going on? Shall I suspect any naughty hacker? Any cure for this? It is miserable. I have to give it up, maybe.

Thanks indeed.
