What is the safest and fastest download manager?

I am using free download manager.the company distributes it under gpl(general public license) license.Its free to download and offers great features that are updated regularly further there's a community which warns each other about viruses,spyware that they face in some downloads. the website where you can download it is http://www.freedownloadmanager.org/

I think "Morpheus" Software and also "uTorrent 1.8" Software
