PC lent et isntable

Bonjour,

Help !
Mon PC rame, est instable et refuse des installations/désinstalations !



Infections et corruption registres ne fait pas de doute...

D'après ce que j'ai vu sur le Forum, j'ai passé un coup de Spybot et CC cleaner, et je viens de faire un Hijackthis (log ci-dessous).
Mais je ne suis pas très à l'aise pour tout résoudre tout seul !

Un spécialiste peut-il m'aider ? Grand Merci d'avance.
