To use BitTorrent for file downloads, you need to install the BitTorrent client software. A BitTorrent client is a computer program that manages downloads and uploads using the BitTorrent protocol.The first client, known as BitTorrent, was created by Bram Cohen, in October 2002.Many subsequent clients have been at least partially based on it. Not all clients were originally built for BitTorrent, having added support for the protocol later on. There have been attempts to package malware as BitTorrent clients, probably due to the availability of many legitimate clients and users’ willingness to try new ones. Most famous are: ABC, Azureus, Bitcomet, Bittornado, uTorrent, XBT.
