How do I get rid of this facebook virus?

[88Ad Infinitum88]

I have some kind of Facebook virus that posts this link about Iphones on my profile. I found the application and deleted it (or so I thought) but it is still posting these messages on my status message box and profile. Can anyone help me?
I've changed my password twice since the start of these posts, and I did not type in my password anywhere. Someone sent me a link on facebook chat that said "is this you?" and I clicked it, and after that, i started getting those messages on my status message.

It's not a virus... someone hacked you when you typed in your FB info into a fake "Facebook" site.. and you thought it was legit.
Make sure to check if you're putting that info to the REAL Facebook..

Just change your password, and they will stop.
