Pb suite à trojan

Bonjour,

j'ai eu un trojan ces derniers jours...
Mon fond d'écran était tout bleu avec un message...
J'ai réussi à éliminer ce problème, mais à présent lorsque je me connecte à internet avec IE, ma page démarre sur la page de PSGUARD par défaut.
voisi ce que hijackthis me donne:
