Virus vs Malware — What’s the Difference?

Many people use the term “virus” to describe any harmful software, but in reality, a virus is just one type of malware.
This article explains the difference between the two and helps users understand how each affects computers and networks.

1. What is Malware?

Malware (short for malicious software) is a broad term used for any software intentionally designed to harm, exploit, or gain unauthorized access to a system.

Common types of malware include:

• Virus – spreads by attaching itself to clean files

• Worm – self-replicates and spreads across networks

• Trojan Horse – disguises itself as legitimate software

• Spyware – secretly collects user information

• Adware – displays unwanted ads

• Ransomware – locks or encrypts files for ransom

Objective:
To disrupt operations, steal data, spy on users, or generate profit for attackers.

2. What is a Virus?

A computer virus is a specific type of malware that attaches itself to legitimate files or programs and spreads when those files are executed.
Once active, it can damage data, slow down the system, or spread to other computers.

Typical characteristics of a virus:

• Needs a host file or program to spread

• Activates when the infected file is opened

• May corrupt, delete, or overwrite data

• Spreads via USB drives, email attachments, or network sharing

Objective:
To replicate, spread, and cause damage to systems or data.
