What is one function of an antivirus program in a computer system?

An antivirus program plays a crucial role in maintaining the security and integrity of a computer system by identifying and removing potential threats such as viruses, malware, and other malicious software. This function is vital because these threats can compromise sensitive data, corrupt files, and disrupt the normal operation of the computer. By actively scanning files and monitoring downloads, the antivirus helps prevent infections before they can do harm. This protective measure allows users to maintain a more secure environment, ensuring their systems operate smoothly and safely without the interference of harmful software.

The other functions listed, such as enhancing gaming performance, scheduling system updates, or monitoring network traffic, are not primary responsibilities of an antivirus program. While some comprehensive security suites may include features related to these areas, the core function of an antivirus remains focused on threat detection and removal.
