there is something wrong with my facebook account?

[Victor]

I accidentally pressed on some link a friend of mine sent me on facebook and now every time I log in it immediately chats almost all of my friends without my permission something like ":)" or a link. I tried deleting the file that was downloaded on my computer when I clicked on the link the first time but nothing happened. I also tried using another browser and using a phone to log in as well. I also changed password. Is there any way I can stop this? It's getting annoying to me and to my friends as well.

try disabling all of your facebook apps to see if that fixes it
