Probleme de virus impossible a suprimé...

Bonjour,
Voici mon problème: à chaque fois que je souhaite éteindre mon ordinateur, juste apres avoir cliquer sur "arréter" mon ordinateur s'arrete et une page bleu apparait à l'écran.
Le pc ne repond alors plus du tout puisque windows à planté.
J'ai découvert il y a peu de temps, lorsque j'ai fais "ctrl atl suppr " pour pouvoir afficher le gestionnaire des taches j'ai remarquer une image du nom de "project1".Je n'avais ouvert aucune image a ce moment la donc j'ai décider de cliquer sur fin de tache de cette image.Mon pc a alors planté et la page bleu met apparue a l'écran.
Dans gestionnaire des taches j'ai (le jour suivant) cliquer sur "project1" pour aller voir le processus de celui-ci.
le processus de project1 est : "dbreg32.exe"
Je pense donc etre infecté par un virus !
J'ai aujourd'hui suivis les instructions de RSIT:
