comodo blocks windows 7 backup

when i try to backupp my computer to a usb drive it gives me the error “problem with shadow copy”, comodo shows in its logs:
“Device\HarddiskVolumeShadowCopy8\ProgramData\COMODO\Cis\Quarantine\data{228AA8C1-C938-4063-83F5-DB765392CD16} detected”

and when i turn off comodo protection i can backup the pc again, how do i make it so i can backup the computer with comodo still running? what is causing this issue?

It looks like cis is detecting files in its quarantine folder when windows backup accesses them. Try emptying the files in quarantine and rerunning the backup

thank you, ill try it now.
