Probleme de virus

Salut,

avast! a détecté 3 virus trojan sur mon ordinateur, et Zone Alarm a repéré windserv.exe qui voulait se connecter sur internet puis un autre winpatch.exe(winpatch.old >>je l'ai renommé) et une autre application suspecte acsdf.exe(acsdf.old>>renommé). Donc ce matin j'allume mon ordinateur et avast! me signale qu'il vient de trouver des trojans après autorisation de windserv.exe à se connecter sur internet(pour le moment j'ai bloqué son autorisation et les 3 trojans sont en quarantaine). Donc les 3 trojans se nomment:
-Nom du fichier : install[1].exe
Description du Virus : Win32:Agent-EIE [Trj]

-Nom du fichier : fasd.exe
Description du Virus : Win32:Agent-EIE [Trj]

-Nom du fichier : fasd.exe
Description du Virus : Win32:Agent-EIE [Trj]

Enfin bref, je vous serais reconnaissant si vous m'aidiez.

Je lance mon rapport HijackThis:
