Malware, a portmanteau from the words malicious and software, is software designed to infiltrate or damage a computer system without the owner’s informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.The term "computer virus" is sometimes used as a catch-all phrase to include 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 U. S. states, including California and West Virginia.
Malware is not the same as defective software, that is, software which has a legitimate purpose but contains harmful bugs.
In this context, as throughout, it should be borne in mind that the “system” under attack may be of various types, e.g. a single computer and operating system, a network or an application.
Various factors make a system more vulnerable to malware:
Homogeneity – e.g. when all computers in a network run the same OS, if you can exploit that OS, you can break into any computer running it.
Defects – malware leveraging defects in the OS design
Unconfirmed code – code from a floppy disk, CD-ROM or USB device may be executed without the user’s agreement.
Over-privileged users – some systems allow all users to modify their internal structures.
Over-privileged code – most popular systems allow code executed by a user all rights of that user.
