I recently attempted to download a key. I was advised by my antivirus software the key contained a trojan horse and it was unable to clean the document so it was quarantined. The file was a small one so I downloaded every available key contained in Limewire. Every one of them was infected by either a worm or a trojan horse. There should be a way to advise Limewire of this type of problem. Someone with less sophisticated virus protection could be infected.
