Virus virulent

Bonjour,
ma fille a validé par erreur sur mon pc un setup.exe qui m'a installé un virus très gênant:
1-réinitialisation du protocole de connection, plus d'internet
2:gestionnaire de tâches bloqué par un soit disant administrateur
3:bureau vierge, impossibler de remettre un image de fond, option "parcourir" grisée
4:pops de messages incessants m'alertant de problèmes a corriger.

J'ai mené les actions suivantes:
1:via core center j'ai tué des processus suspects, lsass a systématiquement entraîné le message bien connu: le pc va redémarrer dans 1mn sur ordre adinistrateur
2:via une astuce de ce forum j'ai delete une clé ce qui me permet d'accéder au gestionnaire de tâches
3: mon pare feu m'a indiqué des ficjhiers tentant de se logguer (frmwrk.exe entre autres), je les ai delete via unlocker.

Grâce à cela je n'ai plus les messages incessants et j'arrive à me connecter à internet, par contre à chaque redémarrage le gerstionnaire n'es plus accessible et le bureau reste toujours bloqué.
