What is the purpose of an antivirus program?

The purpose of an antivirus program is to detect, prevent, and remove malware. This includes a variety of harmful software types such as viruses, worms, trojans, ransomware, and spyware. These malicious programs can compromise system security, steal personal information, or cause significant damage to data and systems.

Antivirus software continuously monitors the system for suspicious activity, scans files for known virus signatures, and offers real-time protection against new threats. By identifying and neutralizing these threats before they can affect system integrity, an antivirus program plays a crucial role in maintaining the security and health of computers and networks.

The other options, while related to computer functionality, do not accurately describe the primary function of antivirus software. Creating backups of files pertains to data management and recovery, enhancing internet browsing speed is related to network performance, and improving system graphics involves hardware and software adjustments for visual output.
