Win32:FakeAlert-FC / Besoin d'aide SVP

J'ai récupérer dans une pièce jointe d'un message un virus qui se présente sous la forme de c.exe et b.exe qui tournent dans les processus. Je peux terminer les processus mais il reviennent sans arret. De Plus Avast détecte 3 ou 4 fois par jour un trojan (Win32:FakeAlert-FC) et me demande de le supprimer via la boite de dialogue Avast mais il revient sans arret.
Ci-dessous le log file de HiJackThis. Par avance merci de votre aide
