Trojan

Bonjour,
Je suis équipé de BitDefender Internet 2008. Ayant des problèmes inexplicables depuis qqe temps, je l'ai desactivé pour passer un coup de SpyBot. J'ai trouvé un Trojan. Pensez-vous que les pb de son avec lesquelles je me bats depuis une bonne semaine peuvent être liés ? Voici le logfile Hijackthis :
