14. A computer-implemented method for assigning reputation scores to entities involved in torrent transactions, at least a portion of the method being performed by a server comprising at least one processor, the method comprising: receiving, by the server, reporting information from at least one computing device that identifies, for each computing device: a target file obtained via a torrent transaction; a plurality of computing systems that were involved in at least one torrent transaction, the plurality of computing systems comprising at least one of: an original seeder that uploaded a torrent file to a torrent hosting site; a peer capable of providing at least a portion of the target file; a peer attempting to download at least a portion of the target file; the impact of the target file on the health of the computing device; assigning, by the server, a plurality of reputation scores to the plurality of computing systems involved in the torrent transaction based at least in part on the reporting information received from the computing device, wherein each reputation score identifies the trustworthiness of the a computing system within the plurality of computing systems involved in the torrent transaction; providing, by the server, the plurality of reputation scores assigned to the plurality of computing systems involved in the torrent transaction to at least one additional computing device participating in an additional torrent transaction that involves the plurality of computing system, wherein the plurality of reputation scores enable the additional computing device to determine whether the additional torrent transaction represents a potential security risk.
