What type of program is designed to detect and remove malware from a computer?

The correct answer is that an anti-virus program is specifically designed to detect and remove malware from a computer. Anti-virus software acts as a security measure that scans the system for malicious software, including viruses, worms, trojans, malware, and spyware. These programs use various techniques to identify malware, such as signature-based detection, which looks for known patterns of malicious code, and heuristic-based detection, which analyzes behavior and characteristics of programs to identify potential threats.

In addition to detecting and removing malware, anti-virus programs often include features for real-time protection, scheduled scans, and updates that keep the software effective against new and evolving threats. This makes them essential tools for maintaining the integrity and security of computer systems.

The other options do not fulfill the same purpose. Adware is a type of malware itself that displays advertisements on a computer, an algorithm is a step-by-step procedure used for calculations or problem-solving, and an array is a data structure that stores a collection of items. These options do not provide the malware detection and removal capabilities that an anti-virus program does.
