Probleme avec explore

Tous d'abord bonjour a tous et je remercie d'avance ceux qui pourront m'aider dans mon problème.
voila depuis peu mon pc (a des moments) devient extremment lent et lorsque je lance le gestionnaire de tache je constate que le processus "explorer.exe" prend 194000 ko ce qui a pour effet d'utiliser 95 pour cent de mon uc je suspecte un virus mais apres plusieurs analyse antivirus je ne trou rien .
je poste donc le rapport hijack effectué en esperant que quelqu'un trouvera une solution a mon problème merci d'avance.
