Onglet s'ouvre seul et liens vers pubs

Bonjour tout le monde!
Voilà tout est dans le titre, quand je suis sur Firefox ou IE8, j'ai des onglets qui s'ouvrent seuls avec des pubs et lors de recherches sur google, les liens me renvoient sur des pub!!!!
J'avais microsoft security essentials qui ne détectait rien, Malwarebytes non plus!!
J'ai mis spybot, qui a enlevé un truc mediaplex!!
ADaware ne trouve rien non plus!!
J'ai désinstallé MSE pour mettre Avira et il me détecte 2 faux positifs que l'on trouve souvent sur des HP!!! (APPL/KillApp.A et 'APPL/ACLSet')

Avant defaire un formatage sauvage, je poste ici mon log Hijackthis et appelle à l'aide!!!!!!
