How reliable is XviD?

[TheSeeker]

I attempted to download it, but then my Mcafee popped up, warning me that I may be downloading a potentially unwanted program.

See, I am trying to find an actor, and I posted an ad on Craig's List, got a response, and the guy gave me a link to his resume on http://resume-post.net/, but in order to view his video resume, I have to download XviD.

I am concerned that this guy could infact just be a spammer since I have gotten spam from Craig's List before after posting stuff.

Xvid is a video codec usually seen for illegal movies not saying xvid its self is illegal but yeah I would not trust it
