mon ordinateur est très lent. Peut-être un trojan ?

Bonjour à tous,
Je rencontre depuis un certain temps des difficultés à me connecter car mon ordinateur est très très lent.
Je vous adresse ci-joint un rapport hijackthis. Pourriez-vous vérifier l'état de mon rapport S.V.P. ?
Avec mes remerciements anticipés.
