My Facebook sent messages to everyone on my friend list by itself?

It's a virus. On Facebook there are always stupid viruses but you just have to stop clicking them and they can't bother you. You must have clicked on one by mistake, but it's happened to me before and I had to go through a lot to get it to go away. What I would say is just to make a new account unless you think you can fix it yourself because if you already changed your password and it's still happening there's nothing else you can do unless you get some type of anti virus package for your internet..
