The Evolution of Malware
In the beginning, people created computers. A few years later, people decided to create malware. Firstly, we need to clarify what malware, virus, worms and trojans are. Malware is a catch-all phrase for all malicious software regardless of how it operates; viruses, worms and trojans fall under the malware term. Viruses spread through computers, firstly through physical input devices and now through the Internet. It usually exists in executable files, meaning it can be on your computer without causing any negative effects until it is run. A worm is a type of virus that can spread without help from a person, for example travelling through an open port in your computer to other computers on your network. Finally, a trojan is a program that allows the creator access to your computer by pretending to be a genuine application (think about the trojan horse).
