about sandbox and D+

hi all

I’ve been wondering the ralations about sandbox and D+.

I click “run out the sandbox next time” when a unknown file run in the sandbox, then I make the rules for this file in D+, ok I think it will under control of the D+ when this file run next time, right? and I also view the log show D+ rules is working normally.

But It is strange that this file also in my trust file list, is it show this file totally trusted by comodo? I cant understand, who can help me?
