CPU 50% tout le temps

Bonjour,

Hier, j'ai fais une analyse de mon ordinateur portable avec Spybot Search & Destroy et j'ai supprimé tous les fichiers dangereux proposés.

Depuis, mon CPU est à 50% dès le démarage de mon ordinateur. Il faut que j'attende environ 20 min pour que le niveau du CPU retombe. Quand je démarre une application (firefox, msn, skype, ...), le CPU monte à 50% pour l'application ouverte et il faut que j'attende 20 min pour que ladite application s'ouvre.

Que puis-je faire ?

Voici mon HiJackThis :
