Méthode préliminaire de désinfection

Bonjour,
mon ordi ramait beaucoup. J'ai donc fait suivi la méthode de désinfection préliminaire de désinfection. J'aurai maintenant besoin de l'avis d'un expert. Je joins le rapport ZHPDiag, et je colle les rapports de MalwareBytes Anti-Malware et de kaspersky online.
Merci d'avance de votre aide

Anaïs
