Besoin d'aide pour un virus

Alors la je vient de me chopper un gros virus... il y a 'Virus Alert!' apparu dans la barre des tache (a côté de l'horloge)
Mon menu démarrer a disparru (jai du le mettre en version 'classique' pour qu'il réapparaisse)
Et j'ai un site (une page blanche) qui ouvre a toute les 5min dans firefox.
Des icône du bureau on également disparu XD
