Abstract: This essay takes an introductory look at computer viruses, covering their definition, the ways in which they spread, the most common types and their impact on digital environments. Based on a theoretical and exploratory review, it discusses signs of infection, dissemination, protection, and practices such as ethical hacking. The methodology was based on a bibliographical survey and qualitative analysis of secondary sources, with a focus on accessibility to readers with diverse levels of familiarity. The study also highlights the importance of digital education in prevention. One limitation is the lack of empirical data and technical depth. Even so, it contributes by broadening the critical view of digital security and encouraging conscious practices. It concludes that strengthening information security requires technical solutions as well as educational actions and effective public policies.
