Virus autorite NT/SYSTEM

Bonjour a tout le monde, j'ai un probléme, a chaque fois que j'allume mon ordinateur, une page s'affiche accompagné d'un minuteur me disant que mon ordinateur s'arrétera dans une minute. Je recule donc mon horloge et cela me donne de la marge pour pouvoir viré ce virus Autorite NT/SYSTEM. J'ai deja telechargé les logiciels adware et spybot. De plus j'ai deja le hijackthis. Voici ce qu'il m'affiche (rapports d'erreurs):
