Trojan Downloader Winfixer E

Bonjour,

J'ai un PC sous WS Me qui plante sans arrêt et rate ses connections une fois sur deux.......J'ai fait un scan Bit Defender V10 et il me dit que j'ai 7 copies du Trojan Downloader Winfixer E dans différentes parties du registre et qu'on ne peut ni les désinfecter ni les déplacer !!!
J'ai aussi fait un scan Ad Aware et un nettoyage avec Ccleaner ( y compris corrections des erreurs) mais les pbs persistent.

Je joins ci dessous le log obtenu aprés l'analyse de Hijackthis :
