There are very few functional, virus-free programs to be had with Limewire. Most will contain viruses, require passwords, be free or trial versions, or be otherwise non-functioning. The makers of Limewire have nothing to do with this. They aren't trying to protect the software companies. They don't put viruses in files.
Limewire is a p2p program...every search hit that you see is a file that is located on someone else's computer. The hits that you are receiving are from users that are currently connected to the network (hence their computers are on). However, if they are limiting their upload bandwidth or are currently uploading to many people, their files may be inaccessible. You can try at other times, as new users are always connecting.
Finally, could you please edit your post and remove the reference to downloading copyrighted material...it's against the
forum rules.
