8. The system as set forth in claim 1 wherein said first feature is a file directory.

9. The system as set forth in claim 1 wherein said first feature is a running process that corresponds to installation of the peer-to-peer client software.

10. The system as set forth in claim 1 wherein said first feature is a code known to be included in peer-to-peer protocol messages exchanged between said target computer and other computers connected to a peer-to-peer network.

11. The system as set forth in claim 1 wherein determining if the multimedia files are stored locally on said target computer further comprises searching all folder and directories on the entirety of the local storage of the target computer for the multimedia files.

12. A method comprising:

reviewing, by a processor of a computer, a first feature of a target computer indicative of installation of peer-to- peer client software on the target computer, wherein said first feature is selected from a group consisting of said target computer's registry keys, registry values, installed executable files, disk directories and network communications;

comparing said first feature of said target computer to first known information indicative of installation of the peer-to-peer client software on the target computer;

reviewing a second feature of said target computer indicative of past participation in peer-to-peer network communication by the peer-to-peer client software on said target computer, said second feature consisting of determining if multimedia files are stored locally on an entirety of local storage of said target computer;

comparing said second feature of said target computer to second known information including at least a predetermined threshold count of multimedia files wherein a search is initiated on the entirety of local storage of said target computer for the multimedia files and the search is stopped when the predetermined threshold count of multimedia files is reached, the predetermined threshold count of multimedia files being indicative of the past participation by the peer-to-peer client software in the peer-to-peer network communication;

determining that the peer-to-peer client software has been installed on said target computer and that files are being shared by the target computer in the peer-to-peer network communication in response to the compare of said first feature matching the first known information indicative of installation of the peer-to-peer client software on the target computer and the compare of said second feature being greater than or equal to the second known information including the at least the predetermined threshold count of multimedia files;
