I can't seem to reach that article. I think my PC need a reboot or something. But, since the software piggybacks on the kazaa network, the only real way to shut it down is to shut kazaa down. Ironically enough.. you can download kazaa lite client through kazaa.. as well as a million other places on the web.
kazaa installs all kinds of software on your computer that monitors your usage patterns, what sites you visit, then sends this information to advertising companies so that the pop ups you get are more likely to be ones that you'll buy into ... spyware can also generally bugger up your system
latest article at the link hi i'm god posted said that kazaa lite may not be down and out just yet
