Shopperreports + ralentissement

Bonjour,

j'ai un souci avec internet :
- lorsque j'utilise internet explorer, j'ai une barre "shopperreports" qui s'ouvre sur la gauche de l'écran à chaque recherche sur google.
- qu'il s'agisse d'internet explorer ou mozilla, tout tourne au ralenti, pourtant ma connexion a l'air d'être bonne.

merci par avance pour votre aide....

voici le rapport de l'analyse hijackthis :
