A computer virus is a type of malicious software program that, when executed, replicates itself by modifying other computer programs and inserting its own code. It can spread from one computer to another through various means such as infected files, email attachments, network connections, or removable storage devices. In the context of tourism, computer viruses pose a significant threat to Information Management Systems (IMS) used by travel agencies, hotels, airlines, and other tourism-related organizations. These systems manage critical data such as booking details, customer information, payment transactions, and inventory, making them vulnerable to disruptions caused by viruses. A virus can compromise data integrity, lead to financial loss, affect operational efficiency, and damage an organization’s reputation if sensitive customer information is leaked or systems are rendered inoperative. Unlike other malware such as worms, a virus requires human action to propagate, for example opening an infected file or running a compromised program. Computer viruses have several distinct characteristics that make them identifiable and impactful on tourism information systems. One primary characteristic is replication. Viruses are capable of reproducing themselves by attaching to files or programs. This replication allows a single infected system to become a source of infection for multiple computers within a network. In tourism, where networks often connect multiple branches, offices, or service points, a virus can quickly spread ________ ___ ________ _____ ________.
