Pub Advertissement

Bonjour,

voila, depuis quelques jours, presque a chaque fois que j'ouvre une page firefox ou internet explorer, j'ai une pub qui s'ouvre avc écrit " advertissement ". Je ferme a chaque fois, ce n'est pas un gros probleme mais j'aimerais bien m'en debarasser alors si quelqu'un pouvait m'aider ce serait cool.

Voila mon rapport :
