The type of malware designed to replicate itself and spread to other computers is called a worm. Unlike viruses, which require human action to spread, worms can autonomously replicate across networks, often exploiting vulnerabilities in software or operating systems. They can consume network bandwidth and cause system failures. Worms may carry payloads that damage files, steal information, or install backdoors for other malicious activities. Effective cybersecurity measures are essential to prevent worm infections and protect systems from their impact.
