Problème d'ordinateur au ralenti

Bonjour,

Depuis hier sur mon PC toutes les applications que je peux lancer fonctionnent au ralenti (navigateur Internet, lecteur média, jeux, etc...), or c'est mon PC portable professionnel, et j'aimerais arriver à résoudre ce problème avant que ça ne devienne trop ennuyeux à supporter au quotidien..!

Je n'ai pas de point de restauration sur cet ordinateur donc je ne peux pas restaurer à une date antérieure, et je n'ai pas installé de logiciels hier avant le début de ce ralentissement continu..! Par contre j'ai prêté cet ordinateur à mon frangin qui lui est fan de poker on-line, donc peut être qu'un spyware ou autre programme indésirable se serait installé à cette occasion sur mon ordinateur..!

J'ai fais un hijack que je vous copie/colle afin que les avis éclairés du forum puissent me venir en aide..!

Merci d'avance à tout ceux qui pourront me dire quoi faire pour retrouver une vitesse d'exécution normale de mes programmes! Pour info je tourne sous Vista sur un PC portable Dell, avec 2Go de Ram et un processeur T7500 à 2.2Ghz.
