Which of the following is NOT typically a feature of antivirus software?

• A. Malware detection
• B. Data encryption
• C. Regular updates
• D. Quarantine functionality

Answer: (B)

Antivirus software is primarily designed to detect, prevent, and remove malicious software, including viruses, worms, and Trojans. The core features of antivirus programs typically focus on malware detection, regular updates to keep the software current with the latest threats, and quarantine functionality to isolate infected files and prevent them from causing harm to the system.

Data encryption, while a crucial component of many security suites, is not a standard feature found in traditional antivirus software. Encryption focuses on securing data by converting it into a coded format that is unreadable without a key, making it a distinct function from malware detection and prevention. Therefore, identifying data encryption as not being a typical feature of antivirus software is correct.
