Infections help please !!!!

Salut alors j'ai un petit probleme avec dre trojans j'en ai déjà éliminé pas mal mais ils reviennent. J'en ai donc déduit que je n'ai pas réussi à choper la source. Sous XP il se manifeste par un lancement de internet explorer au démarrage (page about:blank) puis quand je me ballade sur internet il me balance une pub pour un spyware !!!!!!!
