Avast a trouvé un cheval de troie : Win32:Small-EPJ et rapport Hijack

Bonjour à tous,
Avast a sonné l'alarme et m'a indiqué qu'il avait trouvé le cheval de troie : Win32:Small-EPJ
Il me propose d'abandonner la connexion, mais l'alerte revient tout de suite après.
J'ai lancé spybot et ad-aware, mais rien n'y fait.
Pouvez-vous m'aider à me débarrasser de ce virus, je vous en serais très reconnaissante.
J'ai fait une recherche sur le sujet et j'ai anticipé en téléchargeant Hijackthis. Mais après ?
Merci et à bientôt !

Edit : voici le rapport Hijackthis
