Pops-up intempestifs

Bonjour,
Depuis quelques jours, j'ai des soucis de pops-up s'ouvrant tout seuls à n'importe quel moment par mozilla firefox et en plus, internet explorer ne fonctionne plus correctement puisqu'il rencontre des erreurs qui le ferment. J'ai essayé le logiciel Ad-aware mais le problème n'a pas disparu.
J'ai fait un log hijackthis :
