ESPACE DISQUE DUR DIMINUANT CHAQUE JOUR !!

Bonjour,

comme dit dans le titre chaque jour je viens a perdre plusieurs mega voir giga sur mon disque dur principale C
j'ai vérifié et fait le nettoyage de mon disque dur passant en revue toutes parcelles de mes fichiers sans pour autant trouver une raison valable ni de gros fichiers.
Donc après avoir regarde plusieurs forums sur internet je suis convaincu qu'il s'agit d'un virus
voici mon log malwarebytes suivi d'un log hikackthis :
merci d'avance
