What feature is often provided by antivirus software?

• A. Data visualization
• B. Real-time protection against threats
• C. Hardware installation
• D. File compression

Answer: (B)

Antivirus software is specifically designed to protect computers from malicious threats such as viruses, malware, and other types of cyberattacks. One of the primary features it offers is real-time protection against these threats. This means that the software actively monitors the system for any suspicious activity and can take immediate action to neutralize threats as they occur. This proactive approach helps to safeguard the integrity and security of valuable data and systems, ensuring that users can operate with confidence in a safe computing environment.

In contrast, data visualization refers to the graphical representation of data, which is typically not a function of antivirus software. Hardware installation involves setting up physical components, which is unrelated to the software's protective capabilities. File compression is a technique used to reduce the size of files for easier storage or transfer, and again, this does not align with the core purpose of antivirus software. Thus, real-time protection stands out as the essential feature provided by antivirus programs.
