Spyware
Spyware is software that aids in gathering information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge.[1] Whenever spyware is used for malicious purposes, its presence is typically hidden from the user and can be difficult to detect. Some spyware, such as keyloggers, may be installed by the owner of a shared, corporate, or public computer intentionally in order to monitor users. While the term spyware suggests software that monitors a user's computing, the functions of spyware can extend beyond simple monitoring. Sometimes, spyware is included along with genuine software, and may come from a malicious website. In German-speaking countries, spyware used or made by the government is sometimes called govware. Routes of infection[edit] The installation of spyware frequently involves Internet Explorer. Effects and behaviors[edit]
Portmanteau
Word blending the sounds and combining the meanings of two others Thank you, dear donor! Your generosity helps keep Wikipedia thriving. Select "hide appeals" to suppress fundraising messages in this browser for a week, or go back to the appeal if you're still interested in donating. We ask you, humbly: don't scroll away. Hi. Thank you! Origin[edit] You see it's like a portmanteau—there are two meanings packed up into one word. In his introduction to his 1876 poem The Hunting of the Snark, Carroll again uses portmanteau when discussing lexical selection:[12] Humpty Dumpty's theory, of two meanings packed into one word like a portmanteau, seems to me the right explanation for all. An occasional synonym for "portmanteau word" is frankenword, an autological word exemplifying the phenomenon it describes, blending "Frankenstein" and "word".[18] Examples in English[edit] Jeoportmanteau! Oxbridge is a common portmanteau for the UK's two oldest universities, those of Oxford and Cambridge. Irish[edit]
Computer worm
Many worms are designed only to spread, and do not attempt to change the systems they pass through. However, as the Morris worm and Mydoom showed, even these "payload-free" worms can cause major disruption by increasing network traffic and other unintended effects. History[edit] On November 2, 1988, Robert Tappan Morris, a Cornell University computer science graduate student, unleashed what became known as the Morris worm, disrupting many computers then on the Internet, guessed at the time to be one tenth of all those connected.[3] During the Morris appeal process, the U.S. Harm[edit] Countermeasures[edit] Worms spread by exploiting vulnerabilities in operating systems. Users need to be wary of opening unexpected email,[13][14] and should not run attached files or programs, or visit web sites that are linked to such emails. Mitigation techniques include: Worms with good intent[edit] Several worms, like XSS worms, have been written to research how worms spread. See also[edit] References[edit]

Malware definition – What is it and how to remove it | Malwarebytes
You know how every year the medical community campaigns for everyone to get a flu shot? That’s because flu outbreaks typically have a season—a time of year when they start spreading and infecting people. In contrast, there are no predictable seasonal infections for PCs, smartphones, tablets, and enterprise networks. For them, it’s always flu season. But instead of suffering chills and body aches, users can fall ill from a kind of machine malady—malware. Malware infections come at us like a torrent of water from a fire hose, each with its own methods of attack—from stealthy and sneaky to subtle like a sledgehammer. What is malware? Malware, or “malicious software,” is an umbrella term that describes any malicious program or code that is harmful to systems. Hostile, intrusive, and intentionally nasty, malware seeks to invade, damage, or disable computers, computer systems, networks, tablets, and mobile devices, often by taking partial control over a device’s operations. How do I get malware?
Computer virus
Computer program that modifies other programs to replicate itself and spread A computer virus[1] is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs.[2][3] If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses.[4] Computer viruses generally require a host program.[5] The virus writes its own code into the host program. As of 2013, computer viruses caused billions of dollars' worth of economic damage each year.[10] In response, an industry of antivirus software has cropped up, selling or freely distributing virus protection to users of various operating systems.[11] A computer virus generally contains three parts: the infection mechanism, which finds and infects new files, the payload, which is the malicious code to execute, and the trigger, which determines when to activate the payload.[33] Trigger Payload
Network Access Control
Network Access Control (NAC) is an approach to computer network security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.[1][2] Background[edit] Network Access Control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do. In plain English[edit] When a computer connects to a computer network, it is not permitted to access anything unless it complies with a business defined policy; including anti-virus protection level, system update level and configuration. Goals of NAC[edit] Because NAC represents an emerging category of security products, its definition is both evolving and controversial.

Malware vs Viruses: What's the Difference?
July 27, 2018 | By admin Loading... Understanding the difference between malware and viruses is very important. A virus is just one type of malware, but the term is more widely used by the public. The term malware refers to any malicious software, including a computer virus. Malware is infecting computers and mobile devices at an increasingly greater pace. What is a Malware? Malware is software written specifically to harm and infect the host system. Virus: As discussed, Virus is a specific type of malware by itself. Adware: Adware is also known as advertising-supported software. Spyware: This type of malicious software, spies on you, tracks your internet activities. Worms: This type of malware will replicate itself and destroys information and files saved on the host PC. Trojan: Trojans are a type of virus that are designed to make a user think they are a safe program and run them.

Trojan horse (computing)
To what extent should one trust a statement that a program is free of Trojan horses? Perhaps it is more important to trust: the people who wrote the software.
