What is malware?
Definition
Malware is any software designed to harm, spy on or gain unauthorized control of a device, network or account.
Why it matters
Types include ransomware, information stealers, trojans, spyware, worms and botnet agents. Most malware relies on a user running something or on an unpatched flaw, so updates and careful downloading prevent much of it.
