Infecté par virus. Besoin d'aide Svp

Bonjour à tous,

Suite à différents symptômes bizarres (plantes de logiciels, ralentissement du pc, impossibilité de fermer certains programmes, j'ai décidé de faire un scan Kaspersky. Celui ci a detecté plusieurs infections. Je n'y connais rien en virus, pourriez vous m'aider à résoudre ce problème. Merci beaucoup par avance.
Voici le log Hijackthis et Kaspersky
