Probleme avec spads.dll

Bonjour,
j'ai un problème avec mon ordinateur! J'ai eu un virus en téléchargant un truc sur limewire! Quand j'ai vu ça, mon antivirus (norton) me disait que le virus se situait dans le fichier spads.dll.......alors, je l'ai supprimer (sans trop réfléchir que le fichier était dans le fichier system, sans l'enlever de ma corbeil. Après avoir redémarer mon ordinateur, un message me disant que le fichier spads.dll était manquant est apparu. Alors, je l'ai remis à l'endroit où je l'ai précédement supprimé.

Maintenant, j'ai un problème, quand je vais sur internet explorer, internet se ferme automatiquement...pas toujours, mais souvent. C'est la même chose avec firefox

ps. essayez d'être clair, car je ne connais pas trop les ordi! Merci! J'attend de votre aide :)

Un ami à moi m'a dit que venir ici et de copier coller un log de hijackthis que je viens de faire, alors le voilà!
