Lenteur et plantage subits

Bonjour,

Depuis quelques jours, mon PC portable Toshiba est anormalement lent (ouverture d'un dossier, travail dans Office...) et plante même parfois alors que depuis que je l'ai (4 ans au moins) il a toujours bien fonctionné vu que je fais attention à ce que rien ne s'installe en douce.

Je joins un rapport HijackThis. Merci pour votre aide.
