Problème Systeme 32

Bonjour,
J'ai un problème avec le systeme 32 je ne sais pas ce que c'est, au demarrage on me dit qu'il manque "yayxu.exe" que j'ai surement supprimé du systeme32 par erreur à cause des virus. Mais je ne sais pas comment remettre le systeme 32 dans son état initial.
J'ai déjà restaurer à une date antérieure mais ca n'a rien changé. Merci de votre aide voici le rapport:
