Virus Megaclick

Bonjour,
Depuis plusieurs jours je ne pouvais plus accéder à certains site, j'étais redirigé sur une page "Megaclick Internet adversing". J'ai consulté les différents post sur le sujet et j'ai donc supprimé de Firefox les modules complémentaires Megaclick, scanné mon disque avec Antivir et Trent Internet Security, Réinstallé la dernière version Firefox. Résultat: je n'ai plus la page ""Megaclick Internet adversing" mais j'obtiens à la place une page d'erreur "Connexion réinitialisé".
SVP, pouvez vous m'aider pour résoudre ce problème, n'étant pas une bête en informatique.
Pour info je joins le rapport Hijackthis, car je n'y connais rien mais j'ai cru comprendre qu'il pouvait aider., Merci d'avance pour votre aide.
