What type of software protects against malware?

• A. Antivirus software
• B. System optimization software
• C. Web browser software
• D. Word processing software

Answer: (A)

Antivirus software is specifically designed to detect, prevent, and remove malware from computers and other devices. This type of software works by scanning files and programs for known threats, comparing them against a database of virus signatures, and monitoring system behavior for any suspicious activity. When a potential threat is identified, antivirus software can quarantine or eliminate it to protect the system from damage or data loss.

Other types of software do not serve the same purpose as antivirus software. For instance, system optimization software focuses on improving system performance by cleaning up unwanted files and managing system resources. Web browser software enables users to access the internet and navigate websites, but it does not inherently provide protection against malware. Word processing software is utilized for creating and editing text documents and does not offer any protective features against malware threats.
