LimeWire is not too bad. One thing I discovered is that you can download the Pro version of LimeWire from the free version ... no payment necessary. Obviously someone has allowed it to scan their computer for files to share after they purchased it ... silly them. There are fakes though, just make sure the version number matches what is on LimeWire site. Also make sure you have a good anti virus and updated.

Not with the newest versions since about LW 5.5 because LW Pro is now individually code activated per person's pro account length. And the newest pro versions come with AVG anti-virus.
