VIRUS win32 :tratBHO [trj]

Bonjour,
Je suis un peu débutant en informatique et j'aimerai que qq'un m'aide à supprimer le virus win32:tratBHO que détecte Avast!
J'ai pu apercevoir sur d'autres forum que ce virus se supprimait au cas par cas et a l'aide d'un rapport Hijackthis.
Donc voici ce rapport :
