What is the function of anti-virus software?

• A. To detect, prevent, and remove viruses and other malicious software
• B. To enhance the quality of multimedia files
• C. To create backups of important data
• D. To manage system resources efficiently

Answer: (A)

The function of anti-virus software is to detect, prevent, and remove viruses and other malicious software. This type of software plays a critical role in safeguarding computer systems from various threats that can compromise data integrity and system performance.

Anti-virus programs regularly scan files and programs for known patterns of malicious code, effectively identifying potential threats before they can cause harm. Additionally, they provide real-time protection, monitoring system behavior to catch any suspicious activity as it happens. By maintaining an updated database of malware definitions, these programs adapt to new threats as they emerge, making them essential tools for protecting valuable information and ensuring the smooth operation of computer systems.

The other choices do not align with the primary focus of anti-virus software. For instance, enhancing the quality of multimedia files pertains to editing or managing media, creating backups focuses on data preservation, and managing system resources is related to optimizing performance rather than security. Thus, the answer accurately reflects the core purpose of anti-virus software.
