This is a Trojan that hides itself as a common media file. When the user attempts to open the file, it then downloads malware from an external server. The malware installed on the system will then lead to further serious problems.
If a user attempts to open this trojan, Windows Media Player will open, but it will then prompt for a download of something like “Play_MP3.exe”.
As with any media file, be careful when opening. If the file is not opened and directly played in your media player program, then there could be a problem. If ever prompted to download a .exe when opening a media file, proceed with extreme caution.
