MSN opens conversations

[Strupi]

Hello,
My MSN is opening conversations and send's the next text " Foto hxxp://apps.facebook.com/nnettetoll/photo.php?=lizzyverhoeven@hotmail.com" (the mail adress is from the receiver)
I have run the Avast scanner and windows defender. Nothing helped.
Anyone a solution for this problem?

I'm running on windows Vista
