RSPlug.M Variant of Old Mac Trojan
Currently it has been reported that this Trojan is making it way across the Web hiding on music sites offering music from such artist as 2Pac. Common names of links include "Fast Mp3 Music Downloader" and "MacCinema" and a host of others listed in earlier post which offer to install codecs but instead will install RSPlug.M. Users should not install any kind of video codec or software for that matter which the source is not certified as trusted either by the organization or independent verification.
