"Forty-five percent of the executable files downloaded through Kazaa, the most popular file-sharing program, contain malicious code like viruses and Trojan horses, according to a new study..."

Viruses spread via Kazaa:
Go to and do a search for at 15 February 2004, 103 items were found.

The infamous MyDoom virus was, reputedly, released into the wild using Kazaa and became the fastest spreading virus yet.

Many users are dumping the original Kazaa because of spyware, and moving to KazaaLite, but that does *not* stop the trojan/virus problem.

"SaveNow downloads a small list of promotional websites to your computer. It uses this list to show you offers for products you may be searching for at that time. For example, if you browse to, you may be searching for a book to buy. SaveNow may be aware of a bookstore where you can get a better deal and will show you this when you go to without interrupting your explicit browsing.

The page no longer exists, but some choice quotes included:


"...The EULA, when found, claims that it may clash with various other software and so if it finds any it will remove it. (!)..."


"...As well as removing DownloadWare you should check your system for other things it has installed and get rid of them too..."

Brilliant Digital software installed with Kazaa


"...Two days after disclosures that file-swappers using Kazaa were unwittingly downloading software that could turn their computers into part of a new network, Kazaa's owner spoke up to defend the company's actions.

As previously reported, Kazaa quietly has been bundled for two months with software that contains the core of a new peer-to-peer network. This software, from a California company called Brilliant Digital Entertainment, has been installed on potentially tens of millions of computers. Brilliant Digital plans to "turn on" this software in four to six weeks, tapping the resources of potentially tens of millions of ordinary PCs to distribute content or advertising or to run complicated computer tasks...."


"...Brilliant Digital Entertainment, a California-based digital advertising technology company, has been distributing its 3D ad technology along with the Kazaa software since late last fall. But in a federal securities filing Monday, the company revealed it also has been installing more ambitious technology that could turn every computer running Kazaa into a node in a new network controlled by Brilliant Digital.

The company plans to wake up the millions of computers that have installed its software in as soon as four weeks. It plans to use the machines--with their owners' permission--to host and distribute other companies' content, such as advertising or music. Alternatively, it might borrow people's unused processing power to help with other companies' complicated computing tasks...."
