[Virus] Trojan downloader win32 agent uj

Bonjour, la page d accueil de world of warcraft m a indiqué que j avais le virus trojan downloader win32 agent uj.
En suivant les conseils du forum technique de blizzard j ai ouvert une autre session en laissant wow lancé sur la premiere session: aucun message d avertissement sur le trojan. Mais depuis peu je ne reussi plus a installer les dernieres mises a jour du jeu meme en le reinstallant.
voici le rapport hijack en 1er et ensuite celui de fixwareout:
