Ok so I don't know why, but for some reason my keyboard shortcuts have changed randomly so what I used to turn up the volume with now takes me to dashboard, turn down volume is desktop, to play is spaces, etc. Also it puts a black frame around things that I'm using or have clicked on and if there is text it will start to read it. It's like I have a virus or malware but I can't find anything with scans or virus/malware detection. And I know Macs aren't supposed to have viruses, but this makes me question that. Any ideas on how to fix would be great!
