Avast me donne comme location du virus : D/System Volume Information / -restore{3FA60C-2F2D-4CDC-91}

J’ai aussi comme protection A2 square, SpyBot, Ad awareSE et Spyware Blaster. Y-a-til d'autres programmes que je devrais ajouté à ceux-ci?

Qu’est-ce que je doit faire?

Merci à l’avance de vos conseils.
