Comment desinstaller antivirus 2008

Bonjour, voici quelques jours que antivirus 2008 s'est installeé sur mon ordinateur. Apres diverses tentatives d'élimination avec des antivirus, ce dernier est toujours présent sur mon PC. Pouvez vous m'aider afin de l'éliminer . Je vous joints le rapport de Hijackthis. Merci d'avance. Patrick
