Anyway, I'm with the Professional version and it's very rare to see that message.
BUT:
I'm fully sure that after A P2P download is finished the automated action for this provider is done: the infected file is automatically sent to Chest.
But, the message appears on the bottom of the window...
Silent Mode is disabled into Standard Shield settings.
