Virus introuvable

Tout d'abord bonjours a tous.
Voila, mon probleme est que j'ai un virus sur mon ordi qui s'apel selon mon antivirus (bit def 9) UERSV_0001_N68M0602NetInstaller.exe.
Il ne veut pas l'effacer, avec ad-aware, quand je lance une analyse il bloque sur le fichier.
Hier j'ai fait une analyse ewido, il a trouver 5890 objet infecté, il les a tous nettoyer mais le virus et toujours la.
Le probleme est que je n'arive pas a le trouver dans mon ordi (pour l'effacer manuellement).
Le chemin c'est: E:\Windows\downloaded programme files\ UERSV_0001_N68M0602NetInstaller.exe.
le probleme est que je trouve des fichiers dans ce dossier mais pas sous ce nom.
Je ne m'y connait pas trop en ordi et sa m'embeterais d'effacer nimporte quoi.
J' ai fait un rapport hijackthis et sa me donne sa :
