AntiVirus 360??

Bonsoir, j'ai vraiment besoin d'une aide!! Sa fait presque 1 mois que mon pc semble plus lent et ouvre des page blanc quand je surf sur le net..

a chaque fois que je redémarre IE7 ou Firefox une page s'ouvre et me dit que mon pc est infectées...(en anglais),puis il me propose de télécharger antivirus 360 mais je refuse toujours. En attendant le gestionaire des taches marche pas et IE7 1 fois sur 2.
