Infection trojans+coolwebsearch :(

Bonjour à tous :>

voilà, j'ai un problème de cool web search et plusieurs trojans sur mon pc. Avast détecte les Trojans, mais ne peut que les mettre en quarantaine, et a² avait trouvé 400 fichiers infectés et après plusieurs scans, ceux qui résistent sont des fichiers coolwebsearch.

Voici le log, merci d'avance de votre aide ! ;)
