Virus vs. Worms: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023
A Virus is malicious software that requires user action to replicate, while a Worm is a self-replicating malware that spreads independently across networks.
Virus vs. Worms

Key Differences

A Virus is a type of malware that attaches itself to a program or file, requiring human action to spread, such as opening a file. Worms, in contrast, are self-contained programs that can self-replicate and spread without human intervention.

Viruses often corrupt or modify files on a targeted computer, leading to detrimental effects. Worms primarily focus on spreading across networks, consuming bandwidth and potentially delivering payloads like data theft.

The infection mechanism of a Virus typically involves modification of existing files, making them vectors for spreading the Virus. Worms do not need to attach themselves to programs; they are standalone software that exploits network vulnerabilities.

Viruses can be more challenging to detect due to their concealment within legitimate files. Worms, with their network activity, can be more easily detected but are harder to contain due to their rapid spread.

The primary intent of a Virus is often data damage or system disruption, whereas Worms may aim to create backdoors, allowing for further exploitation or additional malware delivery.

Virus

Any of numerous submicroscopic complex organic objects which have genetic material and may be considered as living organisms but have no proper cell membrane, and thus cannot by themselves perform metabolic processes, requiring entry into a host cell in order to multiply. The simplest viruses have no lipid envelope and may be considered as complex aggregates of molecules, sometimes only a nucleic acid (DNA or RNA) and a coat protein. They are sometimes viewed as being on the borderline between living and nonliving objects. They are smaller than living cells in size, usually between 20 and 300 nm; thus they pass through standard filters, and were previously referred to as filterable virus. The manifestations of disease caused by multiplication of viruses in cells may be due to destruction of the cells caused by subversion of the cellular metabolic processes by the virus, or by synthesis of a virus-specific toxin. Viruses may infect animals, plants, or microorganisms; those infecting bacteria are also called bacteriophages. Certain bacteriophages may be non-destructive and benign in the host; - see bacteriophage.

Virus

A program or segment of program code that may make copies of itself (replicate), attach itself to other programs, and perform unwanted actions within a computer; also called computer virus or virus program. Such programs are almost always introduced into a computer without the knowledge or assent of its owner, and are often malicious, causing destructive actions such as erasing data on disk, but sometime only annoying, causing peculiar objects to appear on the display. The form of sociopathic mental disease that causes a programmer to write such a program has not yet been given a name. Compare trojan horse{3}.
