It's a scene to present a model so it's normal to have cs files. These plugins are not available as var so it can only be embedded.NO CHARACTER REQUIRES A SCRIPT PLUGIN TO RUN. NONE.
open the var file with 7zip or winrar first, find any .cs script files, even if you recognize them and delete them, especially any content from crazy3dmodeler.
But it's messy.. I looked at half, is ok but then gave up. Doesn't look harmfull.
To the original poster, thanks for sharing. Just don't use a bad hoster.
