Démarrage IE et firefox impossible

Bonjour tout le monde !!

Alors voilà mon soucis, pour changer comme une daube, j'ai double cliqué sur un fichier keygen.exe qui a, encore une fois, disparu ! J'ai effectué 1 scan en ligne et 1 autre hors ligne ! Malheureusement aucun virus ou autre n'a été trouvé ! Mon ordinateur a redémarré depuis, mais impossible de démarrer Firefox !

J'ai effectué un scan avec Hijackthis, je copie le log ici pour vous demander de l'aide !

En vous remerciant d'avance !!!
