5 win32 agent help !!!

Bonjour,
Voilà curieuse, j'ai fais un scan de mon disque dur C:, et suite à ça mon anti-virus (avast) m'a détecté 5 petits mignons virus :
Win32: VB-FHB [Trj]
Win32: VB-FHB [Trj]
Win32: Trojan-gen (Other)
Win32: Trojan-gen (VC)
Win32: Agent-SYQ [Trj]

Je les ai mis donc en quarantaine ! Je pense d'ailleur q'un rapport Hijackthis s'impose. J'attends vos conseils !
