Sounds like you downloaded something from p2p, correct? Maybe something that's supposedly not out yet, that looks too good to be true (are the alarm bells ringing yet??) It's not a movie, it's a fake file pretending to be a compressed archive using an new "zix" format. The idea is to get you to download a program called Winzix. THis program is full of adware and spyware. It's a scam. The file is garbage - the point is to get you to install winzix, thus loading your machine with spyware/trojans. Last month it was passworded RAR files directing you to maliciously scripted websites; this month it's winzix. Scams evolve - and you just got caught by the latest variation.
