Soucis Connexion Internet

Bonjour,
J'ai quelques soucis avec ma connexion internet.

Etant belge, j'ai une limitation de download/upload qui se situe a 17,5Go par mois.

Chaque 15-17 du mois depuis un trimestre, je me retrouve avec cette limite de téléchargement dépassée et ma connexion retombe a dû 64kbps.

j'ai installé et lancé HijackThis.

Voici son fichier log après un scan.
