One of my programmer buddies refers to this process as "turd polishing" because, as he says, it doesn't make your code any less smelly in the long run but management might enjoy its improved, shiny, appearance in the short term.
Timeline of notable computer viruses and worms Early academic work on self-replicating programs[ edit ] The first academic work on the theory of self-replicating computer programs  was done in by John von Neumann who gave lectures at the University of Illinois about the "Theory and Organization of Complicated Automata ".
The work of von Neumann was later published as the "Theory of self-reproducing automata". In his essay von Neumann described how a computer program could be designed to reproduce itself. The Reaper program was created to delete Creeper.

Secondly, every computer virus must contain a routine to copy itself into the program which the search routine locates. Infection mechanism[ edit ] Infection mechanism also called 'infection vector'is how the virus spreads or propagates.

The virus will eventually be activated by the "trigger" which states which event will execute the virus, such as a date, the presence of another program or file, the capacity of the disk exceeding some limit or the user taking a certain action e.

Not all viruses have this stage. The virus places a copy of itself into other programs or into certain system areas on the disk. The copy may not be identical to the propagating version; viruses often "morph" or change to evade detection by IT professionals and anti-virus software.
Each infected program will now contain a clone of the virus, which will itself enter a propagation phase.attheheels.com gives you the largest range of Windows and Microsoft news that you can get anywhere on the internet.
