Page internet explorer qui s'ouvrent toutes seules

bonjour

depuis quelques jours j'ai des pages internet explorer qui s'ouvrent toutes seules !!

quand j'allume mon pc et que je ne vais pas tout de suite sur internet 5 min après internet explorer ouvre une page, jamais la même !! alors que je n'utilise même pas internet explorer pour surfer !!

merci pour le coup de main !!
