svchost gourmand en ressources

Bonjour,

J'ai récemment constaté que mon ordi ramait terriblement. Du coup, je suis allé voir du côté des processus et anormalement un des svchost est gourmand en ressources. Je me demande si c'est un virus ?

Si quelqu'un peut analyser Hijackthis, le voici, et merci par avance à mon sauveur :
