Can all Sandbox features be disabled completely?

How can I disable all Sandbox features so I can remove Alternate Data Streams from downloaded files.
I know how to prevent Comodo from permanently labeling future downloaded files, but if files already have Alternate Data Streams attached, I can only clean them if I uninstall Comodo 8.

Going back to Comodo Firewall 7 resolves this problem but is there a way to disable Sandbox completely and stay on Comodo 8… since Sandboxing feature appears to be preventing existing Alternate Data Streams from being removed.

I’m not sure I understand you. Disabling sandbox is easy. Just switch to advanced view on the main screen - upper left corner - and you’ll see the option.
