Going Through the Virus

Now I must said that you have finish studying about the basics of the assembly language, so that I want to continue with our virus writing guide. Before that you must know every types and function of virus you want to create. Remember, all of this is for educational purpose only. I don't want to take any responsibility of what you're doing with my article. For started, there are three types of virii @ virus that is:

1) Tiny virii (under 500 bytes) which are designed to be undetectable due to their small size. TINY is one such virus. They are generally very simple because their code length is so limited.

2) Large virii (over 1,500 bytes) which are designed to be undetectable because they cover their tracks very well (all that code DOES have a use!). The best example of this is the Whale virus, which is perhaps the best 'Stealth' virus in existence.

3) Other virii which are not designed to be hidden at all (the writers don't give a shit). The common virus is like this. All overwriting virii are in this category.


Tiny virii generally do not have many of the "features" of larger virii, such as directory traversal. The third type is more of a replicating trojan-type, and will warrant a brief (very, very brief!) discussion later.

A virus may be divided into three parts: the replicator, the concealer, and the bomb. The replicator part controls the spread of the virus to other files, the concealer keeps the virus from being detected, and the bomb only executes when the activation conditions of the virus (more on that later) are satisfied.

On the next post I will explain briefly to you about the replicator part of the virus and I will provide some of the code. Don't misuse this information! See you again in the next post.
