Three things I find normally find fishy about media files from torrents (music/video/otherwise):
- VLC won't open the file
- Encryption that is not based on a password
- Any mention of a 'special' codec
I would stay far away from this file and find a different version of it elsewhere. The danger is probably not the file itself, but whatever 'codec' you have to download will inevitably contain some kind of malware. Though, if you can provide more specific information about the encryption, someone more informed than myself may have a better answer for you
This is what McAfee have to say about infoavi.com

This site has a link to download a supposed "codec" in order to watch certain video formats. After downloading the .exe file, which already had me concerned, my anti-virus software identified the .exe file as a trojan and immediately removed it.
