Which type of malware is designed to replicate itself and spread to other systems?

A computer virus is a specific type of malware that is designed to replicate itself and spread to other systems. This replication occurs when the virus attaches itself to legitimate programs or files, enabling it to be executed and propagate to new environments whenever the infected program is run. Once activated, viruses can cause a variety of damaging effects, including corrupting files, stealing personal data, or crippling system performance.

The distinguishing characteristic of viruses is their ability to self-replicate and spread through human interaction, such as sharing infected files or using infected devices. This behavior sets them apart from other types of malware, such as spyware, which primarily focuses on gathering information without the user’s consent; Trojan horses, which disguise themselves as legitimate software but do not replicate; and ransomware, which encrypts user files and demands a ransom for decryption but lacks the self-replicating function of viruses. Understanding this distinction is crucial for recognizing the threats posed by different types of malware and implementing the appropriate protective measures.
