Gros ralentissemnt, virus??

Bonjour,
J'ai un gros problème de ralentissemnt, mon pc met beaucoup de temps à s'ouvir, je pense donc avoir un virus. De plus toutes les radios que j'essai d'ouvir me sont refusées le message suivant apparait iexplore à rencontrer un problème et doit fermer, il parraitrait que c'est un virus.
Voici mes rapports ewido et hijackthis. Quelqu'un peut-il verifier et me dire ce qu'il en ai de ces rapports car je ne m'y connait pas assez pour savoir où est le problème.
Merci d'avance
