System Alert: Trojan-Spy.Win32@mx

Bonjour,
Bah voila depuis quelque temps j'ai pas mal de soucis avec mon pc. Sur ma barre de démarrage à coté de l'heure il y a un triangle jaune qui clignote avec plusieurs message different comme: "System Alert: Trojan-Spy.Win32@mx" ou des Fatal Error! . Quand je démarre internet explorer il y a une page: Security Center qui m'annonce en grand "W32.Myzor.FK@yf is a virus that infects files with.exe extensions"... Plusieurs pub sur spyward ...Mais aussi et le plus embetant des pub porno :-s c'est vraiment génant. A j'ai installé Hijackthis et voici mon log (aider moi svp je ne sais plus quoi faire merci) :
