Probleme RPC/lenteursPC :possibilité de virus

Bonjour,

Je suis confronté depuis l'installation du service Pack3 de Windows XP à des problemes de reboot PC automatique suite à un appel RPC.
En lisant un peu sur les forums , on conseille de faire un shutdown -a pour ne pas que le PC reboote seul, et puis on conseille egalement de passer quelques antivirus (online) , qui n'ont rien trouvé à mon probleme.
De plus juste apres avoir lancer la commande précédente, mon PC réagit bisarrement .. je ne peux plus copier-coller, je ne peux plus regarder de videos .mov, je ne peux plus deplacer des fenetres internet , il rame enormement ! jai meme eu des ecrans bleus , et une non reconnaissance de mes ports USB.....

J'ai pensé a vous poster le rapport HiJack.this (qaund le probleme n'est pas encore arrivé), j'espere qu'une personne pourra m'aider à résoudre ce souci, qui je pense est lié à un malware type cheval de troie ou autres.
Je vous remercie d'avance!
