Find out what malware is.

Malware, short for "malicious software," is software designed to harm a computer system, network, or device without the user's consent. Malware can take many forms, including viruses, worms, spyware, ransomware, and trojans. It can be used to steal personal information, damage or destroy files, monitor user behavior, or even take control of a device or system. Malware is often distributed through phishing emails, infected websites, or as attachments to seemingly innocent downloads.
