Demande aide contre le virus "serial99"

Bonjour, j'ai le virus "serial99.com" sur mon ordinateur:
je n'ai plus accès aux gestionnaires des taches comme si je n etais plus administrateur; au demarrage d'internet, j'ai n'ai pas retrouver ma page "yahoo" mais le site d'ou est parti l'infection. J'ai tout de même reussi à réimposer ma page yahoo mais le nom du virus reste indiquée sur la fenetre d'internet explorer au dessus (bande bleue.
Que dois-je faire etant donné que avast et syeraser n'ont rien su faire.

Voici un post logfile que j'ai obtenu apres avoir lancé hijackThis:
