Answer:
Malware can be utilized to damage infrastructure that utilizes computers. It can manipulate what a computer is doing. In this way, a piece of malware could be designed to target government operations, such as government office computers, and then steal and wipe data from a computer. In other ways, a piece of malware could target the water supply control computers, and removing safety features, or target the power grid. This is why infrastructure necessary for day to day life and survival should be separate from the Internet, which can remove a major vulnerability.
