yeah it's quite disturbing BUT
you have to learn how to deal with files and with limewire users (who are the ones who put signs like the garbage one)

for instance:

1) i have downloaded hundreds of mp3 files WITH the garbage sign and none of them was a fake : all of them were ok

2) when you're looking for a movie, there is a trick : when you put the cursor on the file and you do NOT get any information about the size (like 512x288), it's a fake! do not download it!

understood? the sign does not mean a lot at all
