What is the primary function of antivirus software?

• A. To permanently delete all files
• B. To scan and eliminate known viruses
• C. To automatically back up files
• D. To enhance internet speed

Answer: (B)

The primary function of antivirus software is to scan and eliminate known viruses. This specialized software is designed to detect, quarantine, and remove malicious software, including viruses, worms, Trojans, and other types of malware that can harm a computer system or compromise data security. Antivirus programs work by comparing files on a computer against a database of known virus signatures and patterns. When a match is found, the software can either delete the malware, quarantine it to prevent further damage, or repair the infected file.

By regularly updating its virus definitions, antivirus software provides ongoing protection against new and emerging threats, helping users maintain the security and integrity of their systems. This crucial role in protecting devices from malware outbreaks can prevent data breaches, loss of sensitive information, and potential system failures.
