The term for self-replicating code that spreads from one computer to another is malware, specifically classified as a computer virus. These malicious programs attach themselves to legitimate software or files, infecting systems and potentially causing significant damage. Once executed, they can replicate, spreading to other devices through networks or removable media. Viruses can disrupt operations, steal sensitive data, and compromise system integrity. Understanding this term and its implications is essential for implementing effective cybersecurity measures to protect systems from such threats.
