Download uTorrent - a (very) tiny BitTorrent client

µTorrent (or uTorrent; commonly abbreviated as "µT" or "uT") is a freeware, closed source BitTorrent client now owned by BitTorrent, Inc. It is the most widely used BitTorrent client outside China (where Xunlei is more popular). It gets the "µ" in its name from the SI prefix "micro-", referring to the program's small memory footprint: the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet. The program has received consistently good reviews for its feature set, performance, stability, and support for older hardware and versions of Windows.

The program has been in active development since its first release in 2005. Although originally developed by Ludvig Strigeus, since December 7, 2006, the code is owned and maintained by BitTorrent, Inc. The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 and above of the BitTorrent client, a re-branded version of uTorrent.

uTorrent is available for Microsoft Windows, Mac OS X and Linux. A uTorrent Server is also available for Linux. All versions are written in C++.

Bittorent Site Compromised, Serves Malware to Downloaders

Attackers hijacked two popular Bittorrent websites and tampered with their download mechanisms, causing visitors trying to obtain file-sharing software to instead receive malware.

The hacks on bittorrent.com and utorrent.com replaced the sites' standard software downloads with a piece of fake antivirus software known as Security Shield, an advisory warned. Anyone who downloaded and installed software from those sites between 4:20 a.m. California time and 6:10 a.m. should scan their systems immediately for infections.

Once installed, Security Shield delivers false reports that a computer is infected with multiple pieces of malware and prompts the user for payment before claiming to disinfect the machine. The attack affected only users who downloaded and installed software from bittorrent.com and utorrent.com during the hour-and-fifty-minute window that the sites were compromised. Those who installed software previously are unaffected.

"We take the security of our systems and the safety of our users very seriously," the Bittorrent advisory stated. "We sincerely apologize to any users who were affected."

Bittorrent Client Released uTorrent 3 Final

After what felt like an eternity, the final version of the popular lightweight Bittorrent client uTorrent 3 has been released today. The final version is build 25406 and existing users should see update notifications when they start their client on their system, or by manually checking for updates by selecting Help > Check for Updates. Users of uTorrent 2.x can download the latest version of the program from the official website, where it is available as a 32-bit and 64-bit application for the Microsoft Windows operating system.

The release notes are as usually available on the official forum. Version 3 of uTorrent adds features such as a portable mode, streaming, torrent ratings or drag and drop sending of files. The complete list of changes and fixes is available in the forum.

The drop files to send feature is incredibly easy to use. Just drop a file that you want to share on the drop area, and uTorrent will create the torrent for you. The program displays a tiny url link that the recipients of the file need to open. The torrent is then added to their uTorrent version. If they do not have uTorrent it is installed on their system.

Streaming needs to be activated in the uTorrent options before it becomes available. All suitable media players are automatically available for selection in the options.

The Stream button becomes then available in the torrent listing. A click on the button loads the stream url in the selected media player. It is then possible to play the media in the player directly, even if it has not been downloaded completely yet.

Depending on your previous version, you may see a different looking client with additional features that you had not had access to before. This includes uTorrent apps which more often than not provide access to media and file releases of companies and organizations. You find some apps among the available ones that add features to uTorrent, a chat for instance.

The getting started guide in the client seems to be new as well. It offers a step by step guide, a beginners guide and links to faqs and information about the program (correct me if I’m wrong here).

The developers have fixed a boat load full of issues, from crashes and stability issues over freezes and hangs to cpu optimizations.

Users should take a look at known issues before they update, if they want to make sure that the program works on their system without difficulties. The list displays confirmed problems and issues that are not fixed in the uTorrent 3.0 stable release.

Most of the bugs listed seem to be limited to display issues, only a few indicate stability issues.

On a personal note. I’m running uTorrent 3.0 since the first alpha and did not have a single problem ever since. The update to version 3.0 went without difficulties. Some users in the release thread are on the other hand reporting problems with the version.

Have you made the update to uTorrent 3.0 yet? What is your impression of the new version.
