Virus et connection

bonjour a tous et joyeux noel !
voila j'ai un souci sur mon pc depuis 2 jour
j'ai telecharger une video et quand j'ai voulu la lire on m'a propose de telecharger un genre de codecs
depuis quand je veu me connecter sur IExplorer
la fenetre s'ouvre c'est ecrit connection en cour puis rien ne se passe je ne peu pas fermer ni ouvrir quoi que se soit
je suis oblige d'eteindre l'ordi en restant appuye sur l'interupteur
auriez vous une solution
merci d'avance
