When I type the letter "c", I get the letters, "dc". When I type the letter "d", I get "dc." For the letter "e", I get "3e" on the screen. The same thing happens for several characters on the keyboard of my Toshiba laptop. I just received the new keyboard that I ordered and the same thing happens. My deductive reasoning tells me that the old keyboard was good. Does anybody have any ideas? Is there a virus that does that?
