How do you remove "Checkmessenger2.net" from the Windows Live Messenger?

I tried the Checkmessenger2.net site to see how it works, but after analyzing my MSN/Widows Live messenger, I noticed that in chats my user name appears as

"http://www.CheckMessenger2.net %26lt;--Find out who deleted you from the MSN without noticing it!!!"

I wrote to the website for instructions on how to get rid of this but they won't respond. Does anybody know how to remove this from my messenger and get my user name to appear again in chats? Thanks!
