Answer: (B)

The primary function of antivirus software is to detect and remove malware threats. This involves scanning files and programs for known malicious patterns or behaviors, as well as monitoring the system for any unusual activity that could indicate an infection. Antivirus software often utilizes a database of malware signatures to identify threats and employs heuristic analysis to uncover new or unknown malware by examining the behavior of files.

By effectively identifying and mitigating malware infections, antivirus software plays a crucial role in protecting the integrity of the user's data and maintaining overall system security. This function is essential in safeguarding computers and networks from potentially damaging software like viruses, worms, trojans, and ransomware, ensuring that users can operate in a safer digital environment.
