Trojan-Dropper.Agent!IK à retirer manuellemen

Bonjour,

A-squared free a détecté "Trojan-Dropper.Agent!IK" qu'il ne peut supprimer. Il me dit de le retirer manuellement.
Pourriez-vous m'indiquer la marche à suivre si possible?
En vous remerciant de votre aide.

Je ne sais pas si çà peut vous servir mais j'ai effectué un scan avec HijackThis et je vous poste le résultat:
