This has been discussed a lot lately. Perhaps you couldn't find the forum search button. But the answer is to get the newest LW version & it stops these spam files having this effect. http://www.limewire.com/english/content/download.shtml

When you see search results like 100 or one, 99 for next, etc. go further down the list & choose those with 10 or 20 sources. The Overpeers, etc. are spamming the network with such files when people search for copyright material. Those with 100, etc. are fake.
