There's a piece of spyware going round on msn that sends you a message from one of your contacts urging you to see a picture of someone. The link is usually a crafted URL that try's to look like a imageshack URL. Once you click the URL an I-frame in the page injects the source into your computer and enables the attacker to read your msn messages.
