Hijackthis?

bonjour,

je me retrouve avec une barre de recherche non désirée et une page de demarrage qui remplace la mienne regulièrement. après consultation du forum, je suppose qu'il s'agit d'un pb de type Hijackthis.
j'ai fait l'analyse mais malgré le tutoriel, je n'y vois pas clair.
pouvez vous m'aider à retrouver la lumière?
voici le rapport.
d'avance merci
