What is a Zombie?
“Zombie” is becoming the common term for a computer that has been effectively hijacked by someone else. A zombie might be used to relay spam, attack other computers, or simply share copyrighted files and programs (called warez). In many cases, these are the result of a virus, worm, or trojan horse, but once the computer has been turned into a zombie, there may be no trace of the original infection. It may take professional help or complete removal and reinstallation of the operating system to regain control of a computer that’s been made into a zombie.
