Des centaines de Delivery Status Notification

Bonjour,
Je reçois dans ma boîte mail des centaines de messages ayant pour objet :"Delivery Status Notification (Failure)?" provenant de "postmaster@mail.hotmail.com" avec une pièce jointe de type "Hello.eml" et le message suivant : "To all of my friends who didnt have the opportunity to see me on the channel 4 news last tuesday discussing my blog, and financial-success story. I am sending you the News story, so you can read the entire story on how I learned how to become financially independent and wealthy. Here</a". Quelqu'un peut-il m'aider à exterminer cette chose ? Merci d'avance.
J'ai fait un rapport avec Hijackthis le voici :
