CONT

Computer viruses ... are best defined by four essential characteristics: ... 3. Side-effects: Viruses do not normally consist only of self-replicating code; they also contain a "payload". This is comparable to a missile carrying a warhead; the self-replicating code is analogous to the missile and the side-effects to the warhead. It is easy to program the payload side-effects to be malicious.

CONT

You can significantly shorten the program code of a virus by not including a new copy of the manipulation task with each virus. You can keep the manipulation task on the mass storage and have the virus place a call to the manipulation program within the host program.

CONT

Les virus informatiques [...] peuvent être définis par quatre critères essentiels: [...] 3. Les effets secondaires: en général, les virus ne sont pas uniquement constitués d'une codification autoreproductrice; ils contiennent également une «charge». On pourrait faire une analogie avec un missile transportant une charge explosive; la codification autoreproductrice est analogue au missile et les effets secondaires à la charge explosive. On peut facilement programmer les effets secondaires de la charge pour qu'ils soient malveillants.

CONT

On peut alléger considérablement le code d'un virus en évitant d'y inscrire la tâche de manipulation. Celle-ci est alors enregistrée une seule fois dans la mémoire de masse et le virus se contente de graver dans chaque programme infecté un simple appel à un certain «MANIP.EXE».
