Hijack un peu d'aide

Bonjour,
je ne comprends rien a Hijack et mon vista est pleins de lourdeur ces derniers temps, le disque tourne sans cesse et le ventilot est souvent en train de tourner à mort !

si qqln peut jeter un oeil, j'ai un portable asus sous vista avec antivir, windows defender, je viens de passer spybot mais sans détection.

Merci !
