Démarrage très long

bonjour,

mon ordinateur semble bloqué lors du démarrage sur un processus avwsc.exe qui demarre et s'arrete pendant au moins 15mn.
j'ai telechargé hijackthis, fais un scan dont vous trouverez le compte rendu ci dessus.
Quelqu'un pouurait il y jeter un oeil et me dire ce qui cloche et quoi faire
je vous remercie par avance
Carole
