Avast :mise en quarantaine impossible

Bonjour,
J'ai installé avast et j'ai lancé un scan. A chaque fois qu'il detecte un virus je cliquais sur "mettre en quarantaine".
les premiers ont été placé en quarantaine sans probleme mais arrivé à un certain nombre il a commencé à m'afficher "Espace insuffisant sur le disque impossible de traiter le fichier"
J'ai generé un rapport avec HijackThis mais je n'y comprends rien; si quelqu'un peut m'aider.
Voici le contenu du fichier généré:
