I picked up some nasty malware called Omiga, I googled how to get rid of it which involved installing an adware program I didn't previously have, ran it and now my keyboard doesn't work neither does my Xbox 360 controller. When I boot up the keyboard lights come on but later in the start-up process they go off and the keyboard doesn't work. It's a PS2 keyboard btw. Thank for any advice or help, it's doing my head in because most of my games are now unplayable.
