SOS Trojan virus?????

mon pc est hyper ralenti depuis quelques temps, il serait infecté par le trojan virus

après voir un peu suivi les conseils que j'ai pu trouver sur le forum, j'ai lancé 2 fois le escan (2 fois car j'avais oublié de copier la fenêtre "virus log information!)

voici ce que me dit ce compte rendu ce matin :
