Pc rame et supprssion fichier impossible

Bonjour, mon pc rame depuis une bonne semaine, j'ai essayé de résoudre le problème avec des infos glanés ici et là sur le forum, mais c'est toujours pas ça

voici le rapport du scannage de mon pc avec Hijackthis.

Pourriez vous m'aider en me disant ce que je dois faire ?

Merci d'avance
