What defines a computer virus?

A computer virus is defined as a piece of code capable of copying itself and typically causing harm to the computer system or its data. This self-replicating nature is a fundamental characteristic of viruses, allowing them to spread from one system to another, often without the user’s consent or knowledge.

Once a virus infects a system, it can disrupt normal operations, compromise files, corrupt data, and even breach security protocols, leading to more severe consequences like data loss or unauthorized access to sensitive information. This malicious behavior is a distinguishing feature that sets viruses apart from other software programs.

In contrast, options related to improving system security, managing files or facilitating data recovery do not capture the essence of what constitutes a computer virus, which fundamentally relies on its ability to replicate and potentially harm systems. By understanding this definition, one can better recognize the importance of protecting systems from such threats.
