Intro to VB viruses

Many of you people out there will stop reading this article just by the title of it. Most asm coders are really prejudiced against High Level Language viruses and especially Visual Basic ones. Here I guess I would have to greet Murkry for writting the first ever parasitic VB virus. After that I learned many stuff and used some methods of my own which I will teach you through this series of tutorials.

The only reason why I even started writting VB viruses was that I was a macro coder and I wanted to try exe infection. This was my first contact with exe infection. VB viruses have one b i g flow. That is their size. As you all know they are big and that is something we don't want in a virus is it? To solve this problem we could use variables for oftenly used string to shorten the code but that isn't much help so we have to accept the size as a flow and try to find many tricks to make it as hard to detect as possible. Another problem of VB viruses is that they need dlls to run(!) not a thing we want for a virus. Besides this is why I started learning asm. VB viruses are for educational purposes only.

You can use encryption for VB viruses as well. I have used character encryption ( used in macro viruses, first used by VicodinES ) and it worked succesfully. Now I am trying to find other methods of encryption especially for VB viruses and you will see the results in later issues of this series.
