3wplayer is a rogue media player software application bundled with trojans that can infect computers running Microsoft Windows. It is designed to exploit users who download video files, instructing them to download and install the program in order to view the video. The 3wplayer is infected with Trojan.Win32.Obfuscated.en according to Kaspersky Anti-virus.
The 3wplayer employs a form of social engineering to infect computers. Seemingly desirable video files, such as recent movies, are released via BitTorrent or other distribution channels. These files resemble conventional AVI files, but are engineered to display a message when played on most media player programs, instructing the user to visit the 3wplayer website and download the software to view the video. The program is bundled with malware that has various undesirable effects, including attempting to disable anti-virus software.
Wildman Productions has created a tool to convert video files compressed for the 3wplayer back to regular AVI files. More details can be found on their site. http://wildman-productions.org/
I downloaded this movie, and it told me that in order to watch it, I needed to download a media player called 3wplayer, and it gave me a virus once I did.
