Swoopy, if I'd you, I'd immediately uninstall it. It has troijan horses (?), which takes connections to different places without you knowing it (if you don't have updated internet security software like Norton Internet Security, that is). Anyway, using Kazaa like p2p softwares, you will get virus, sooner or later.
Using Kazaa Lite about 2 months now, I've already received several viruses / troijan horses that Norton Antivirus has blocked off.
Be extremely careful and get good antivirus software (and internet security), if you don't have ones yet. IMO Norton products are best possible out there.
