Problème de ralentissement et compagnie.

Bonjour,et merci pour votre aide future.

Voila après la suppression d'un Trojan.Vundo (par Vundofix, Combofix et Bitdefender) mon ordinateur subit de nombreux ralentissements. En effet, j'ai en permanence 500 Mo de RAM utilisés. De plus, il m'arrive d'avoir des erreurs STOP IRQL_NOT_LESS_OR_EQUAL sans raisons. Malgré mes efforts pour résoudre le probleme : utilisation de CodeStuff Starter pour enlever les programmes unutiles au démarrage, vérification hardware (pas de problèmes), et utilisation de la commande sfc/scannow dans cmd pour vérifier mes fichiers windows... rien à faire.
