A 1993 movie, directed by
Rachel Talalay, starring
Karen Allen and others (according to
IMDB, and this stuff is sketchy because I didn't watch the movie that well =)
The plot is somewhat like this: A serial killer works in a computer shop. He steals his victim's address books, and kills people listed in them, one at time. Now, one lady forgets her address book to a computer shop - she bought a program called Paper Warrior that scans an address book and puts it into a digital form - handy, that.
Now, this serial killer guy wants ends up into a car accident and dies. Or, not really. He turns into an electronic entity that lives in the power grid and electronic devices. He takes the recently-scanned address book, and uses his mad skillz to kill people in various ways.

BAD movie, pretty predictable and not great feats of acting... Even kids with bad grades in physics and computing stuff would groan at the absurdities of the movie. =) However, the concept of the movie is pretty interesting and it features some cool stuff of its era (old VR equipment, old Windows boxes in the computer shop, etc...)
Half-decent excuse to spend a night...
