What is the ruling on downloading computer programs that enable the user to download video and audio clips from the internet, and downloading programs that open blocked websites, and programming a receiver to receive channels?

It is permissible to download download managers, except for those who know or predominantly believe that they will use them for unlawful purposes. In such cases, downloading them is not permissible as it would be assisting in sin. As for programs that unblock restricted websites, they are predominantly used for unlawful purposes, hence downloading them is prohibited unless one knows that they will be used for permissible purposes. Programming a satellite receiver for channels is generally permissible for lawful channels and prohibited for channels that broadcast unlawful content.
