Query: DANGER - INSTALLS UNAUTHORIZED SOFTWARE

If you run Windows XP, do not insert this (or any Sony BMG) CD in your computer. Without prompting for permission, it will install a cloaked 'Root Kit' on your hard drive that can interfere with the proper operation of your computer and leave it vulnerable to hacking and virus attacks. This software is very hard to remove too. This just happened to me. My firewall did not stop it and it destroyed my anti-virus program and several of my system tray applications. VERY BAD STUFF. YOU ARE WARNED. You can search "Sony BMG Rootkit" on one of the big search engines for more information.
