Can you explain it a little better? What type of macbook do you have. More specifically, what type of keyboard? Is it a "chicklet" keyboard? It could be the keys are jammed or something caught underneath it. I wouldn't worry about it being a virus cause this sort of thing happens with trojan horses on windows.
