Virus ? ouverture de fenetre publicitaire

bonjour à tous,

je viens ici pour vous demander votre aide.
depuis un long moment j'ai des soucis d'ouverturs de fenêtres publicitaire, ralentissment de l'ordinateur et même des fermetures de l'ordi.
mon deuxième ordi que j'ai depuis 5 jours lui aussi m'affihce depuis hier des pubs, celui-ci on verra plus tard, si je n peut pas faire les deux en même temps, une chose à la fois.

j'ai bitdefender comme antivirus, avant j'avais avast;
je viens d'installer zone alarm.

merci d'avance pour votre aide, attention je n'ai que très peu de connaissance informatique.

j'ai fait un hijackthis à l'instant , voilà ele rapport
