Unblocking Video Assets Created With Internet Based Software.

Greetings, I have a question about the video files I upload. I use a internet based editing program that once I edit and convert my files with it, it is blocked for security reasons. You know like when you right click to display the files properties and at the bottom it states "This file came from another computer and is blocked for your security". 

It's a result of using an internet based editing program. My question is should I unblock it prior too uploading it since it came from my computer and I am the one who made it, or should I leave it blocked when uploading so that the end user can do so if they feel the need? At first when I started uploading them they seemingly take much longer time than usual to upload and I thought it was a result of not unblocking them however, I've uploaded a few more and they all have been approved. So should I or shouldn't I? Many thanks for any help and have a great day!
