One thing to be aware of is that windows does apply the MOST restrictive set if permissions are set to be inherited, so do NOT have your downloads folder as a sub-folder in any of the "special" system folders, ie: Program Files, Windows or "Application Data".

This is because you will be giving the "Everyone" security group "Full Control" to your downloads and you do not want the higher restrictions of those folders being applied to the open downloads folder. And it avoids the small risk of a directory traversal attack starting in your download location and being able to use the ../ path syntax to 'traverse' the folder tree and access other locations on the drive.
