SVP problème grave avec un Hijack

Bonjour à tous,

je sais que mon problème semble courant mais j'ai déjà eu des attaques du genre CWS et j'y suis toujours venu à bout simplement. cette fois-ci cela semble plus compliqué.

la page de démarrage change automatiquement pour une "about : blank" sur laquelle je vois un champ de saisie et "quick web search" et de nouveaux liens sont systématiquement ajoutés a mes favoris : classique.

sans paniquer j'ai d'abord vidé mes fichiers temporaires, l'historique IE blablabla

puis j'ai executé Norton, Ad-aware, SpybotS&D et surtout CWShredder, le tout en mode sans échecs avec chaque logiciel mis a jour... donc là je suis à court de solutions.

voici le log pondu par HIJACK THIS :
