Re: safe file sharing sites ??
HotdogsFolks is right, uploading copyrighted material is illegal.
But if you are going to go down this road do it properly.
First of all get a good spyware and anti virus remover to undo the damage you've already done.
Most of these programs contain malware and spyware that slow your machine and compromise your machines security. You need to address that issue first.
Then know that the progs mentioned, Morpheus, limewire and others like Kazaa are infected with this spyware and malware and they screw up your machine.
Winmx is old (near dead) but it's the best of a bad bunch, imo, it's good if you are looking for individual songs.
Bit Torrent is undoubtedly best at the moment for sharing, download a client like Azureus, then go to websites like mininova.org and download the torrents from there, open the torrent in Azureus and it will download the file from there. Torrents work best with full albums and movies, it's not great for singles.
Beware about downloading software, they are usually carriers for Trojans and Viruses (or Virii if you want to be pedantic). As a rule of thumb don't download any file that is an exe, zip or rar.
