Méchant virus win32

Bonjour,
Jai deux méchants trojan dans mon système32 et je n'arrive à m'en défaire car il se ré-installent toujours aussitôt que je rebranche mon modem

Est-ce qu'il y a une gentille personne qui pourrait me donner des ptit conseils sans que j'aies à formater toutes mes données ??

Merci de votre aide !!
