Malware
From Computing and Software Wiki
Malicious software (malware) encompasses a broad range of software typically designed to covertly operate and deceive users to hide its actual intended purpose. It can be used as a catch-all phrase for software that has been programmed for malicious purposes intentionally; software such as viruses, worms, spyware, and botnets. Its purpose can vary, but typically it is used to gather information, generate profit, cause harm or data loss, or it could have no real purpose at all.

History
Before computers were accessible to the general public, malware was not an overwhelming threat. Starting sometime in the 1970's computers became somewhat more common, and as a direct result, so did malicious software. At this time, viruses started to appear on networks such as ARPANET, gaining popularity into the 1980's with the explosion of person computers. Early malware was typically less of a threat, created by programmers who were trying to prank other users, rather than the typical malware created for todays society.
