Internet bots (short for robots) are computer programs that run automated tasks over the Internet. They are used to fetch and analyze information from Web Sites and servers faster than any human can. They can be used to catalogue Web sites for fast searching or do comparison shopping to find the lowest price on an item you are looking for. Malicious bots can be used to hijack unprotected computers, recruiting them in to botnets that launch spam email campaigns, denial-of-service attacks or online fraud schemes.

Cookies, also known as Web cookies or HTTP cookies, are simple pieces of text information created by a Web server and sent to a Web browser (such as Internet Explorer or Mozilla Firefox) on the user's computer and stored to be resent when the server is accessed again. Cookies are often used legitimately by sites to track a user's visit ("shopping carts") for example, often use cookies to store items the user is considering purchasing). While cookies are incapable of performing any operation alone, they have been of concern for Internet privacy since they can be used to track browsing behavior and maintain specific information about users without their consent. For example, they can be used to track your surfing habits without your knowledge and target advertising to you accordingly. Most browsers have settings allowing users to decide if they want to accept cookies. Rejecting cookies makes some legitimate Web Sites unusable, however.

The record can be monitored by the person who installed the device or program. They are sometimes used by employers to monitor employees' computer usage. They can also be installed maliciously through a Trojan horse or spyware, allowing your information to be transmitted to a third party. Because they monitor keystrokes, the can allow someone to find your passwords, account numbers and other information you may not wish others to know about.

Multi-level marketing (MLM) is a business model that uses salespeople to both sell products and recruit additional salespeople from whose sales they will then earn a royalty. New salespeople are often required to pay for their own marketing materials, or to buy a significant amount of inventory. Illegal pyramid schemes follow a similar model but, instead of generating commissions from the sale of products, they generate their income by taking advantage of the salespeople themselves (by requiring salespeople to buy more than they can be expected to sell, for example).

Protecting PII has become more important in an age where the Internet and information technology have made collection and reselling of this data easy and profitable.

Phishers are people who engage in phishing, which is described on our Web Site at Phishing & Spoofing.

A secure server is a Web server that uses the industry standard Secure Sockets Layered protocol (SSL, designated in your browser address bar as HTTPS) or the much less used Secure Hypertext Transfer Protocol (designated S-HTTP) to encrypt and decrypt data so that third parties cannot tamper with sensitive information. The SSL protocol has been described as a secret handshake between a Web browser and a Web server: essentially, the browser will only talk to the server after the server has proven that it knows the handshake. Making purchases over a secure Web server ensures that your payment or personal information will be translated into a secret code to be transmitted over the Internet.

Spyware is a program that installs itself on your computer without your consent and tracks usage and surfing habits, often with the aim of deploying customized and unwanted advertising. Aside from being an invasion of privacy, it may generate annoying pop-up ads, slow your system to a crawl, redirect your computer to Web Sites you never intended to visit, monitor your Internet surfing, or even record your keystrokes.

See our Safeguarding Your Computer page to learn how to protect your computer.

Viruses are computer programs or scripts that infect computers without the knowledge or consent of the user and attempt to replicate and spread themselves to other files or computers. Once they have infected a computer, viruses can cause poor performance, system crashes, lost or corrupted data and more. Viruses can spread themselves from computer to computer in a variety of ways, including email attachments, downloads, across networks or via a removable medium such as a USB drive, CD, or floppy disk. See our Safeguarding Your Computer page to learn how to protect your computer.

A worm is a type of virus that resides in a computer's memory and replicates itself, usually spreading to many other computers on a network. Worms often inflict damage simply by consuming bandwidth and clogging up networks as they duplicate and pass themselves from computer to computer.
