Under Windows 98SE, the keyboard is blocked. I can't shutdown properly, when opening a notepad, it's automatically filled all the lines with the hyphen key. The same occurs if I make a search or wanted to run a program (Start, Run or Start, Find) the hypen keys is automatically activated so that I can't write anything neither even deleted it. If I open Explorer and click with the mouse on a folder, somethimes, this occurs also.
Example : ---------------------
I'd like to be sure that I'm not infected, thanks in advance.
PS: CD drive and USB key are working on it. Mouse is ok.
