Sfc scannow cannot repair

Bonjour,
j'ai la version vista edition familiale premium, j'ai avast comme antivirus et zone alarme comme firewall.
Mon pc portable rame et en plus lorsque je vais sur internet soit par mozilla soit par internet explorer, je perd la connection puis en réessayant de redemarer mozilla il me met qu'1 mozilla est en cours d'execution et de le fermer. Hors fermer ce processus est impossible ac le gestionnaire des taches, bref le bordel. desinstaller mozilla ne change rien.
Je me suis dc dit que j'avai une merde sur l'ordi.
J'ai donc fait un sfc verifyonly puis un sfc scannow et j'ai effectivement des merdes sur l'ordi!
J'ai tenté de les reparer en mode sans echec ca marche pas non plus il me met qu'il peut pas les reparer.
je joint le detail du fichier sfcdetails.txt :
