Also I would not recommend downloading anything without having antivirus this website actually does have antivirus that I used every once and a while to check that everything is clean but I do not trust anything other than my personal virus scan. This goes for other websites too. In my opinion the only way to ensure safety is to have security on client side and that is up to them. Also images, videos and especially rar and zip files can be infected much easier than a demo file can.
