Many computer users are unfamiliar with the term, and often use "computer virus" for all
types of malware, including true viruses.
Software is considered malware based on the perceived intent of the creator rather than
any particular features. Malware includes computer viruses, worms, trojan horses, most
rootkits, spyware, dishonest adware, crimeware and other malicious and unwanted
software. In law, malware is sometimes known as a computer contaminant, for instance in
the legal codes of several American states, including California and West Virginia.
