Ghost in the Machine (1993)

He’s known as "The Address-Book Killer," a murderer who steals strangers’ personal information then targets them for his grisly sprees. But when a freak electrical surge zaps his dying body into a computer mainframe, he’s unleashed online to slaughter the friends and family of Terry Monroe. Now, no place or appliance is safe. Every impulse brings the carnage closer. How do you survive - and ultimately destroy - a madman who can massacre from anywhere?
