It seems like in the example, Joe’s virus would get to the lab faster for analysis. But Avast says, that the submission goes to the lab with the next update, so I would guess that both users would be on the same playing field. If there are, other than maybe to do tests for false positives, what would the purpose of manually sending files to the lab be? The program will pick it up and the lab will do testing when the next definition file goes out anyway. Whether this is by user request or automatic. At least that is how I am interpreting this.

There is a good manual use I suspect, if you just want to Add Files to the chest you are not sure about and send copies to the lab for study.
