J'ai un gros probleme avec mon pc

Bonsoir,

Es ce que quelqu'un peut m'aider, mon ordi fait que planter, j'ai toujour des messages de pub qui s'affiche sur mon écran quand je suis sur internet et de plus quand je suis sur msn mon ordi envoi à mes amis un message et un fichier.

Pouvez vous m'aider, je sais pas quoi faire ?

Je vous joint le rapport Hijackthis :
