Hi Lance and Welcome to the Gnutella Forums.
Unfortunately many of the Nasties that are spread by means of the Gnutella Network are maliciously loaded by companies hired by the RIAA and the MPAA. They do this purposely to discourage file sharing.
There is very little that can be done against these criminals as their IP addresses change very frequently and is almost impossible to block.
Anyone can basicly put anything and everything on the network, which in turn puts the responsibility on us to protect ourselves. The forums are loaded with Great Information on what to be aware of and other suggestions that will help you have a favorable P2P experiance.
