If you have ever seen, read or heard anything about computer viruses in the media, take the time to watch this video all the way through.
I explain what a computer virus is, how it infects a program or file, spreads and activates its payload. We then move on to its life cycle, the different infection methods and the main families: boot viruses, macroviruses, retroviruses, polymorphic and metamorphic viruses.
I also discuss the methods that allow them to change form or attack protective mechanisms, then the very common confusion between computer viruses and worms. The goal: understand what really lies behind the words, beyond media shortcuts.
