I doubt this worm checks if your MP3 collection is legal or not... What's even worse, not all people have just illegal MP3 files in their computers. I for one have a lot of MP3s that I created myself, where my little daughter is actually starting to speak... her very first words. That's something that shouldn't make RIAA concerned. Not to speak about my own music that I've been creating for the last 12 plus years.
