[IE] barres d'outils indésirables

Depuis ce matin je ne peux plus modifier ma page de démarrage (about:blank "quick web serach") et deux barres d'outils (FreshBar et Virtual Maid) se sont ajoutées. Comment faire pour règler ces problèmes?
J'ai déjà utiliser Spybot, CWSchredder et Ad-Aware, rien n'y fait...
Voici ce que me donne HijackThis. Merci d'avance pour votre aide
