Have you herd that Sony Corp now has a program on their music CDs that installs to your root files to prevent you from making more than 3 copies of the CD. Becide the fact that now there is a program on your computer that you didn't put there... Hackers have already found ways to use this program to get into your computer. The Sony software aparently has a few flaws. There are many topics around the internet about this... Here is one of them. Really all you need to do is search "Sony BMG" and you'll come up with all types of pages on this. Symantec has already put out a removal tool for the program that Sony installs on your computer. You can find it here.
Remember though, if you use this tool to remove the file, next time you use the CD it reinstalls it :-\ Sony has put out a "repair" where it replaces the program with a "safe" version... You can find that here.
