What is a computer virus?

• A. A software designed to enhance user experience
• B. An application that reduces system performance
• C. A type of malicious software that replicates itself by attaching to other programs
• D. An error in a software system

Answer: (C)

A computer virus is defined as a type of malicious software that replicates itself by attaching to other programs. This description encompasses the fundamental characteristics of viruses: they can spread from one computer to another by inserting themselves into legitimate programs or files, thereby compromising the system's integrity and security. When a virus infects a host program, it can execute harmful actions, including data corruption, unauthorized access to sensitive information, and even system malfunctions. This self-replication feature is what distinguishes a virus from other types of malware. Viruses can often remain dormant until certain conditions are met, at which point they execute their malicious actions. Understanding the concept of a computer virus is crucial, especially in the context of cybersecurity and personal computer management, as it underlines the importance of using antivirus software and practicing safe browsing habits.
