Virus chopé et msn bug

Bonjour,
hier je jouai a wow et un pote ma envoyer un message me disant " va voir ma nouvelle photo".
le message comportant facebook dans son nom , je ne me suis pas méfier et j'ai saisi l'adresse .
la un message me demande d'executer et rien ne se passe ensuite.
Ce matin, quelle belle surprise de voir que msn débloque a fond( ouverture intempestive de mes contacts, fenêtres qui clignotent, et pour finir msn se coupe tout seul), le pc est ralenti.
Pouvez vous m'aider svp?
j'ai fait une analyse malware et toujours le virus
je vous envoi le rapport hijackthis
