Freeze when preview some of the movie file

When I entering some of the folder that contains some movie files, I have a preview on the right side, and when I choose a file, it popup a window called "ActiveMovie Windows", and it freeze at all. How can I remove this?

You have a bad video codec installed which is producing that error, or the registry settings aren't correct for the type of video in question and the wrong viewer is being used.

See the Enable/fix playback of various media formats in Opus FAQ for suggestions.
