Glossary of Malware Terms
Adware – short for advertising-supported software. Adware is a program or software that displays ads on your computer, redirects your search requests to advertising websites by hijacking your browser, changes your web browsers homepage and collects personal data on you for marketing purposes. Learn more about Adware.
Bot – a self-propagating program designed to infect a user and connect back to command server(s) that act as a command and control center for an entire network of infected users or a "botnet". With a botnet, attackers can launch broad-based network attacks on servers and other entities. A machine infected with a bot is often refered to as a "zombie".
PUP – PUP is short for Potentially Unwanted Program. These programs are typically not malicious themselves, though they can often come bundled with other adware programs. YouTube downloaders, certain weather apps, news notification apps, and couponing apps can all be considered PUPs. Learn more about PUPs.
Trojan – a software program that installs onto a user's machine without consent of the client, often disguising itself as legitimate software. Unlike a virus, a trojan cannot copy itself nor infect files. Trojans are used by cybercriminals to gain backdoors to a user's machine to steal personal data, or load malicious software such as ransomware through a backdoor. Learn more about Trojans.
