OpenOSX‘s TrojanDefuser allows you to deal with files that are suspected of being the recently (8 April 2004) discovered Trojan Horse “MP3Virus.Gen”. If the file is type “APPL” (application), then it will be considered suspect.
TrojanDefuser works by making a copy of the potentially suspect file without a resource fork, prefixing the file’s name with “SAFE_.” The original file is left intact. OpenOSX said it has developed the TrojanDefuser software to work for variations of the same concept embedded in various file types in addition to MP3 files.
OpenOSX is offering TrojanDefuser to Mac users free of charge; the software is being distributed under the GNU General Public License (GPL). [Via: Mac Central]
