remove ad from display name on messenger

I just received an email supposedly from one of my contacts saying "look who
deleted you from their contact list" and it directs you to a webbsite
www.santomessenger.com where you enter your hotmail information including
your password and it has all of your contacts and it gives you info on your
contacts. Now when i sign in my contact see a little display saying that
"www.santomessenger.com fijate quien te ha borrado" has just signed in. How
can i remove it? I changed my display name and still showing. It's a Ad.

I think the real question is what possesed you to give your hotmail username
and password to a random website? Security: not just for everyone else but
you.
