Many PC users consider malware, viruses, spyware, adware, worms, Trojans, etc. as the same thing. While all these infections harm our computers, they are not the same. They are all types of malicious software that each behave differently.
The word malware is a combination of two words “malicious” and “software”. It is a generic term used to describe all of the hostile and intrusive program codes including viruses, spyware, worms, Trojans, or anything that is designed to perform malicious operations on a computer.
The meanings of many of these words have changed over time. Some refer to how the malware infects your system while other words are used to describe what the malware does once it’s active in your machine.
