Yes... Limewire has always installed spyware. More specifically - CYDOOR which Symantec's products have always considered as a Trojan Horse. If you are truely offended by this instrusion then you can get a freeware product by LavaSoft called AD-AWRE which will identify it, as well as most other spyware programs, and assist you in removing it from your system.

BE AWARE... Limewire will no longer run once you've done this. Effectively you are choosing not to use Limewire anymore.

I've tried other file sharing products and still think Limewire is far superior, so one needs to make a consious decision as to how much of an intrusion this CYDOOR is and what it means to them.

Hope this helps...
