What is the primary function of antivirus software?

• A. To manage network bandwidth
• B. To search for behavior typical of viruses and warn users
• C. To prevent unauthorized access to systems
• D. To manage user identity and access

Answer: (B)

The primary function of antivirus software is to search for behavior typical of viruses and warn users. This involves scanning files and programs on a computer for known viruses, malware signatures, and potentially harmful behavior. When these behaviors are detected, antivirus software typically alerts the user and may take action to quarantine or remove the malicious software to protect the system from further harm. Antivirus programs rely on a combination of signature-based detection, which uses predefined lists of known malware, and behavior-based detection, which identifies new, previously unknown viruses by examining code behaviors and flagging them as suspicious. This capability enables antivirus software to proactively safeguard information systems from a wide array of threats, maintaining the overall security posture of the user’s computer or network. The other choices refer to functions that are outside the primary purpose of antivirus software. Managing network bandwidth pertains to network management tools, preventing unauthorized access relates to firewalls and access control mechanisms, and managing user identity and access involves identity management solutions rather than antivirus capabilities.
