Since works of Fred Cohen and Leonard Adleman, describing viral payload (offensive routine) as not being a virus' features, the world of the computer virology has down evolved. To this end, viruses have evil properties in the scientist population and not scientist, this is why viruses have make a new aggressive and deceptive market, with a common word : money. Out of this system, vxers have done beautiful programs, which once are formalizing, become even more interesting in their study. In this paper, I wanted to come back to basic computer virology, having a virus with a real ability to spread, and generate a new virus which is different at each time, but with new mechanisms. Using Linux to build a virus isn't harebrained, each system may be contaminated, and Linux supply interesting qualities to make easier a propagation. Furthermore, using a script language as python can expand the possibilities of interaction with the various components of the system and its vicinity. The k-ary codes are an idea of Eric Filiol, and are a new kind of virus. Inside this paper we have implemented a real one, it will be explained and detailed.
