What is a virus in computer terminology?

• A. A legitimate software program
• B. Malware that duplicates itself and spreads
• C. A type of navigation tool
• D. An antivirus solution

Answer: (B)

A virus, in computer terminology, refers specifically to malware that has the ability to duplicate itself and spread to other computers or devices. This type of malicious software attaches itself to legitimate programs or files, often without the user's knowledge, and is designed to infect other systems by moving between devices through methods such as email attachments, shared networks, or removable drives.

The defining feature of a virus is its self-replicating capability, which allows it to spread and potentially cause harm by corrupting files, stealing sensitive information, or degrading system performance. Understanding this behavior is crucial for recognizing the importance of cybersecurity measures and the need for antivirus software to detect and remove such threats.

In contrast, legitimate software programs are created for productive purposes, navigation tools assist users in finding information or using software features, and antivirus solutions are designed specifically to combat malicious entities like viruses, rather than being viruses themselves.
