when you add manually (file is not detected) it is only a copy
When you manually add a file to the chest,you are doing this with the thought that the file you want to add is something bad.
if you think the file is bad, upload and test it at www.virustotal.com first. ;)
if detected, then you can add to chest and upload to avast lab
and you can always delete file in orginal location if you want....
