Malware is any type of software designed to harm a computer system, network, or server. Its intent is to steal, encrypt, corrupt, delete or alter data and hijack core computing functions leading to data breaches and lost productivity.

Modern malware carries out its attacks in various ways. It may spread through email attachments, peer-to-peer (P2P) file sharing services, free software download bundles, or through a compromised website. Mobile devices are also increasingly vulnerable to malware, especially if they are jailbroken or running unofficial app stores.

Viruses, worms, bots, spyware, rogue security software, rootkits, and ransomware are some of the most common types of malware. They are all built with malicious intent, but the way they damage a computer and their impact varies greatly.

Worms, for example, self-replicate and spread from one computer to another. They can infect entire networks and are notoriously difficult to stop. Bots are similar, but are typically used for malicious purposes to launch broad remote-controlled attacks. They can form a network of bots known as a botnet that is then used to target businesses with massive DDoS attacks.

Adware bombards users with unwanted ads, and is often embedded in programs that are downloaded from the Internet. It generates revenue for the program distributers by displaying unwanted pop-ups in web browsers. Spyware gathers information like browsing history, keystrokes and sensitive data for a hacker without the user’s knowledge. The most popular type of malware is ransomware, which encrypts files until the victim pays a ransom.
