The qBittorrent P2P download program is an upgrade of the famed uTorrent. Of course, qBittorrent is free to download, and also meets the demands of those who downloaded uTorrent, notable for being in Spanish, English, Italian, Portuguese, French, German, etc.
The QBittorrent GUI is an exercise in cleaning up the uTorrent image, but beyond aesthetics, qBittorrent convinces the user by its advanced torrent file search, for its ability to perform searches simultaneously in several websites that host bittorent files, for its ability to organize search categories (eBooks, music, videos, movies, etc.), and for much more.
As an alternative to the uTorrent program, qBittorrent stands out for its compatibility with all extensions of BitTorrent (Peer Exchange, DHT, Full encryption, BitComet, etc), for its ability to be used via remote control, for its excellent management of download queues, for its IP filtering capacity (qBittorrent is compatible with eMule and PeerGuardian), etc.
NOTE: From the website you can also download a version of qBittorrent for Mac OX and Linux.
