In this chapter you will get a good undserstanding about computer viruses including what they are, how they are written, what do they do, and how to fight back.

What is a computer virus?

A computer virus is a program which mutates/infects other trusted programs in such a way that they also become like it. A computer virus mainly consists of 2 main modules 1) A Replicator/Infector and 2) Payload/Bomb. But for a program to be considered a virus just having the first module is enough, payload or bomb can be null, even then the program would be considered a virus. etc/openvpn/server. This in effect means a program may be doing no harm to other (say it has no payload/bomb) but the fact that it is spreading itself by attaching itself to trusted programs makes it a virus.

This replication or capability to mutate trusted programs is important for a virus' survival.

Say there's a program which deletes all the files when run, the simple action you would take to get rid of it is do a search and delete all copies of it from your disk.

But a real computer virus works a little differently, it has got first the "Spread" stage, in which it infects other trusted programs by adding copies of its Replication module (so that these in turn can affect others) and Payload module. Section Navigation. During this time, Payload module will not do anything but stay silent. Only when this "spread" stage is over by meeting "Virii Coders" criteria, like "Have we infected 10,000 files?", if yes, then its showtime. So when its in showtime stage, it would have already infected all your favourite programs like notepad, media player etc. Well, you know when a person is bitten by Dracula you see teeth marks on his/her neck, but there's no such easy identification way here.
