I belive Limewire is on its way down. Lately i have noticed the massve amount of files infected with viruses. Example: T-872159-Roller Coaster Tycoon 3 Soaked.zip
Click for more information about this threat : W32.Alcra.B

I have had 3 instances of this one today and many others. In my opinon the developers should setup a virus reporting system or work on different ways to filter out known bad files
