One of the most confusing scenarios is when a computer becomes infected with malware since the infection can be referred to as viruses, malware, adware, spyware, rootkits, etc. Some of these terms have the same meaning, some are sub-categories, and some are even just simply network tools. Some of the different forms of malware can be trojans, worms, hacktools, password revealers, etc. depending on the purpose of the program.

Essentially, it is the broadest term to cover all forms of infections.
