15. Untraceable

When it comes to Hollywood boogeymen, there are zombies, there are vampires, and there are...computers. We've always had an uneasy relationship with technology, and these movies sum up those feelings better than most.

For example: Do you have a piece of duct tape covering your computer's webcam? You may after watching "Untraceable" (2008). FBI agent Jennifer Marsh (Diane Lane) investigates a mysterious website that films a string of seemingly unconnected murders. As more people find out about the site, more people start to die. But as she gets close to solving the case, her own life and loved ones are thrown into the line of fire.

14. Tron

This 1982 Jeff Bridges classic is about a computer engineer who tries to break into a computer’s mainframe after having his work stolen by a co-worker. Instead he gets sucked inside the computer and has to find his way back to reality through a series of simulations. The sequel ("Tron: Legacy," 2010) was scary for a totally different reason -- lines like, "Biotechnical jazz, man!"

When Bennett stumbles upon a conspiracy, she gets mega-hacked, and ends up in a race to save her identity.
