Three reasons not to download:
1. IT'S NOT THE MOVIE. I REPEAT, IT'S NOT THE MOVIE.
2. There is a virus attached. The exact make and model, we weren't able to figure out but it had a few similar 'code lines' (computer-geek-speak is not a language I'm at home with) as the Love Bug virus.
3. One of the comments below the link included some helpful warnings that indicated if you go past the virus, spyware, tracking ware and adware that are next to impossible to boot will follow shortly after.
I found this link last night before bed and since checking this morning, it has been taken down along with similar links with similar titles. The website (a low-quality torrent site) does very infrequent checks of it's links but given that the thing had close to 150 downloads when I saw it (!!!!!!), there was probably a large amount of complaints being issued. I'm not a member of many websites for Twilight so if you hear something someplace else about a download of the film, (1) that's illegal and (2) please post up this information. I don't want people to lose computers over RPattz JBF hair.
