يمكن الكثير منا لا يعلم الفرق بين الفيروسات والديدان وغيرها الكثير ويطلق على الجميع فايروس
ممكن يكون صحيح من ناحية انها كلها قلق لكن يختلف الضرر حسب النوع والوضيفة

(Computer Malicious Codes (CMC [/align]
[align=left] Virus This CMC transmits malicious codes to other programs and modifies or destroys them .
Viruses usually infect boot sectors of hard discs or specific files such as COM,EXE or macros.
They are relatively easy to detect and remove from systems, although this does take time and requires continuous updates. However, damage may already have taken place.
WORM
The worm is a CMC that disseminates copies of itself through networks by self-replication. It does its damage by overloading the computing power of the central processing units (CPUs) in the network.
Trojan Horse:This is a deceptive piece of software hidden inside a harmless program, an example being the log-in software that requires the user to insert a user name and password when entering a computer network.
The Trojan Horse retains a copy of this data to be exploited later by unauthorized users.
Logic or Time Bomb :This is a program that sits silently inside a computer system and is activated when specific conditions occur such as a particular date, or operational conditions.
Trap Door:This CMC allows unauthorized users to freely enter a system without the operators knowing it . in some cases the intruder can obtain privileges such as system manager , and is able to modify the operating software according to his needed within the computer system without anyone ever knowing
