Download.trojan.Analyse du logfile Hijiack

Bonjour a tous,

lorsque je me connecte a internet explorer, j'ai instantanement un message d'erreur qui apparait et ma page internet qui se referme.

Mon norton qui est desactive (je ne peux plus le reactiver) m'a indique que mon ordinateur etait infecte par "download.trojan"

Ci dessous est mon dernier logfile sous Hijack :
