What is the difference between spyware and spyware dll?

Spyware is a type of malicious software designed to gather information about a user without their knowledge, often to track their online activities or steal sensitive data. A "spyware DLL" specifically refers to a Dynamic Link Library file that contains code or functions used by spyware. Essentially, while spyware is the broader category of malicious software, a spyware DLL is a specific implementation of that spyware, often used to facilitate its operation within a system.
