Processus iexplore.exe parasites au démarrage

Bonjour à tous,
j'ai depuis quelques temps des processus iexplore.exe qui se lancent automatiquement au démarrage et qui occupent une bonne partie de la mémoire de mon pc. Comment faire pour les supprimer ?
voici le log obtenu avec hijackthis.
Merci d'avance

Philippe
