What is the primary function of anti-virus software?

• A. To enhance computer graphics
• B. To protect against viruses and security threats
• C. To accelerate the performance of software applications
• D. To manage hardware drivers

Answer: (B)

The primary function of anti-virus software is to protect against viruses and other security threats. This software is designed to detect, prevent, and remove malicious programs that can harm a computer system or compromise its data integrity. By continuously scanning for known threats and monitoring for suspicious activity, anti-virus software ensures that users remain protected from viruses, worms, Trojans, and other types of malware.

Additionally, the software often includes real-time protection features that can alert users to potential threats as they arise, helping to mitigate risks before any damage occurs. Regular updates to the virus definitions and scanning algorithms are vital for the effectiveness of anti-virus solutions, as new threats emerge frequently.

While enhancing computer graphics and accelerating software performance may be relevant to other types of applications or software, they are not the responsibilities of anti-virus tools. Similarly, managing hardware drivers falls outside the scope of what anti-virus software is designed to do, as that task is typically handled by other system utilities or the operating system itself.
