The rapid development of technology, and its usage, in our everyday lives caused us to depend on many of the aspects it offers. The evolution of the Internet in recent decades has changed human life drastically as accessing knowledge, communication, and social interaction, became readily available. Nowadays, we have become dependent on our PCs and smart devices in accomplishing everyday tasks. People are using these devices to store valuable information. This information became the target of cybercriminals who are constantly creating new ways to gain unauthorized access to it. In the past few decades, cybercrime and the construction of malicious software (malware), have seen a significant rise. In this research, we present a literature review of the historical evolution of malware. We describe the common characteristics and propagation methods for the types of malware in each phase of its evolution. Furthermore, we illustrate the purpose of its creation and the damages it has caused. The purpose of this study is to provide researchers with background about malware and its evolution leading up to present day threats
