Malware

A program that is inserted into a system, usually covertly, with the intent of compromising the confidentiality, integrity, or availability of the victims data, applications, or operating system or of otherwise annoying or disrupting the victim.

A piece of code – either on a webpage, in an email attachment, or an application – that performs actions that the user did not agree to. These actions typically involve providing access to the user’s computer by the perpetrators, logging keystrokes, or redirecting internet traffic.
