This is a story that does not start with “once upon a time” and does not end with “and they lived happily ever after”. This story is about the concrete jungle, it's about the wild world we live in. This is a story about the ugly things that happen behind the scenes while the show must go on... this is the story of the fight for survival of two operating systems.
Many believe that Mac OS and Linux not having virus is a myth or it's because less people use it or whatever reason they make up. The bottom line is that these operating system are simply more secure than Windows. Since Windows dominates 90% of the market it seems like viruses are a normal thing to happen on a computer. The good news is that there is a way out of this.
To better understand how the software industry works it's important to get a clear idea of the origins and the strategies of each operating system and how history unfolded to make things the way they are today.
