Rapport HijackThis pc infecté ou pas ?

Bonjour,

J'ai de plus en plus de pub qui s'affichent à l'ouverture de certains site, c'est vraiment énervant je voudrais vraiment virer ça pour cela il m'est naturellement venu à l esprit que le pc avait des chances d'avoir un virus ou autres. c'est pourquoi j'ai fais une analyse HijackThis, j'aurais aimé savoir selon vos analyse d'expert s'il mon pc est infécté ou si il y a un fichier "douteux" sur mon ordinateur. De ce fait, voici le rapport de HijackThis :
