Message intempestifs

Bonjour
j'ai besoin de votre aide car, comme de nombreuses personnes, je me vois recevoir a chaque connexion internet de nombreuses publicités intempestives.
J'ai donc téléchargé Hijackthis et je vous transmets les résultats.
A partir de cela je voudrais savoir quelle demarche serait necessaire de suivre.
Merci d'avance
