Cheval de troie récurrent avec Avast

Bonjour,

Voilàa j'ai un message d'avast qui me signale un cheval de troie sur mon PC. Le problème s'affiche toutes les 30 secondes sans qu'il n'y ait d'améliorations.

Après avoir chercher sur internet, les gens ayant eu de l'aide ont commencé par un scan hijackthis.

Je post donc directement mon rapport dans ce message, si vous pouvez m'interpréter ce rapport et me dire quoi faire...

Merci d'avance

Ama
