Ordinateur lent

Bonjour,
ayant déjà eu un soucis sur mon ordinateur qui a été dépanné grace a votre site,je reviens vers vous pour un soucis internet je me suis aperçu que dès que l'ordi est connecté a internet il devient de plus en plus lent jusqu'à afficher un écran bleu et aussi Outlook express devient de plus en plus lent jusqu'à ne plus répondre, et quand je suis connecté sur le réseau sans internet ou Outlook je m'aperçois que mon ordi est ralenti pour d'autre travaux voilà mes soucis je vous serai très reconnaissant si quelqu'un avait une solutions a mon problème, je joint avec ce message un rapport hijackthis pour vous donner plus de détails.
J'espere avoir été assez clair
merci d'avance
cordialement
