Virus sur mon PC

Bonjour à tous,
Je viens d'avoir hier une alerte de virus... J'ai avast, Spy-Bot et Ad-Aware.
Cependant, lorsque Avast m'annonce ce virus, j'ai beau faire "supprimer" ou "mettre en quarantaine" ou "rien faire".... Rien ne marche. Je recois un message comme quoi il ne peut pas etre traiter... Que faire?
De plus, j'ai Spyware Quake 2.0 qui s'est installé tout seul. Dans la barre des Taches, j'ai aussi une alerte de virus (un rond barre rouge qui clignote... ainsi qu'un triangle jaune avec un point d'exclamation à l'interieur....)
Si vous savez comment regler ca... merci d'avance... j'ai beau scanne tout mon PC... rien a faire, je ne peux pas le supprimer...
Merci d'avance
bye

EDIT: Fichier: C:\windows\system32\mssearchnet.exe\[Upack]
Nom du logiciel malveillant: Win32:Zlob-BM [Trj]
type: Cheval de Troie

DEs que je met supprimer, j'ai ca: Impossible de traiter le fichier: C:\windows\system32\mssearchnet.exe\[Upack]

Merci pour ta reponse.
