Most modern email services include virus protection in the form of scanners for incoming mail, embedded content, etc. These scanners are also responsible for policing intended attachments for malicious files. However, for individuals seeking to study virus/trojan/malware behavior, this may actually serve as a bothersome impediment. This is especially so for those who wish to exchange a specimen and lack other means of doing so.
Thus this little application.
With some quite trivial coding, it reverses the order of a file. Thereby the AV scanners are fooled by the change in the file's signature. Simply send the file, reverse again to return it to its original state, and voila!
