What is the function of antivirus software?

• A. To create backup files
• B. To prevent, detect, and remove malicious software
• C. To optimize software performance
• D. To assist in software installation

Answer: (B)

Antivirus software is fundamentally designed to safeguard computer systems from malicious software (malware). Its key functions include preventing, detecting, and removing malicious software, such as viruses, worms, Trojans, ransomware, and spyware. By continuously scanning files and programs, antivirus software can identify known threats and quarantine or eliminate them before they can cause harm to the system. The prevention aspect involves actively blocking and filtering out threats before they can infect a device. Detection involves recognizing when malware is present, using a combination of signature recognition and heuristic analysis to identify abnormal behaviors and patterns indicative of malicious activity. Removal is conducted through the deletion or quarantine of identified malware to restore the system to a secure state. In contrast, other choices mention functions that do not align with the primary purpose of antivirus software. For example, creating backup files is related to data protection and recovery rather than malware management. Optimizing software performance pertains to enhancing operational efficiency, while assisting in software installation is about setting up applications which also falls outside the antivirus software's scope. Therefore, the correct answer accurately captures the essential role that antivirus solutions play in maintaining cybersecurity.
