Infection System 32

Bonjour.

Mon System 32 à été infecté par un virus, j'ai formater, mais depuis la RAM et le processeur patine dans la choucroute en utilisant toute leurs ressources, donc je suis surement encore infecté. j'ai beau scannée avec AVG mais il ne trouve rien, j'ai fais un scan hijackthis (que j'ai renommé ) et sa donne ça :
