Lenteur de internet explorer 7

Bonjour,

Depuis quelque temps internet est très lent , firefox idem voire impossible ,message soit je ne suis pas connecté, soit il y a une erreur dans l'adresse
google est ma page de démarrage et quand j'ouvre IE , j'ai l'impression que quand je clique sur IE avant que ne s'ouvre google il y a ouverture de plusieur adresses
J'ai telechargé hijackthis et suivi leur procédure quick start et voici les résultats
Je précise que mes enfants possèdent un PC fonctionnant en wi fi (live box)et que leur connexion est très rapide
N'étant pas informaticien merci de bien vouloir me répondre dans un language compréhensible pour mon niveau ( ne vous fiez pas à mon pseudo)
