Rapport HijackThis -- PC infecté ?

Bonjour,

Depuis quelques semaines, mon PC perd régulièrement la connexion Internet (toutes les 5 mn).

J'ai fait un scan HijackThis dont le rapport figure ci-dessous.

Est-ce que quelqu'un pourrait me dire si mon PC est infecté ou si l'origine de ces coupures à répétition est à chercher ailleurs ?

Merci d'avance
