Which type of software is an antivirus?

Antivirus software is a type of utility software that is designed to detect, prevent, and remove malicious programs such as viruses, worms, trojans, and spyware from a computer system. Its main role is to protect your computer from security threats that could damage files, steal personal information, or disrupt the performance of the system.

Utility software is a category of software that helps manage, maintain, and optimize computer hardware and software. It includes tools like disk cleanup, file management, backup programs, and antivirus software. These programs do not perform the core functions of the computer like the operating system does, but they are essential for keeping the system running smoothly and securely.
