Cheval de troie risque de sécurité norton

Bonjour,
Je pense avoir un virus ou un cheval de troie sur mon pc. Mon Norton Internet security me lance des alertes de sécurité à intervalles régulier avec le nom suivant: trojan.Zbot!gen3

Malwarebytes' et spybot ne le détectent pas.

J'ai trouvé ça sur internet :
http://community.norton.com/t5/Norton-Internet-Security-Norton/svchost-exe-trojan-problem/m-p/182620

Si quelqu'un peut m'aider à l'enlever.

J'ai mis ici le log de Hijackingthis:
