Kazaa
In order to install the Kz, you have to connect to www.kazaa.com and follow the links to the download process. Here lies a trap though. While in the beginning you start downloading a file sized only 588kb, you finally realize in the installation process, that some new files whose length is over 8MBmust be downloaded.

The installation menu is very easy and you just need to follow instructions, agree to the terms of use and give your permission for the adware software.

At the end of the installation, a lot of adware will have been added to your PC which will have to be running so that the Kazaa functions properly (anti spyware/adware software can spot them but they are unable to remove them completely). As soon as you have completed installation, you can run Kazaa without having to reboot your computer.
