How Does It Spread?
The main question is "How does it spread?" The worm spreads itself by sending messages from the users account to all their friends. The message usually includes a subject like, "You look stupid in this vid" or "I got you a camera". The link to the video will then bring you to a third party site and it will say you need to update to the latest Adobe Flash Player, and it will ask you to download it, most people will without thinking. Once the worm is installed its called to action.
