Spyware is software that attaches itself to a computer over the internet, without you knowing. It gathers information about a person or organization by looking at the data stored on your hard drive and may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge. Whenever spyware is used for malicious purposes, its presence is typically hidden from the user and can be difficult to detect. Spyware can collect almost any type of data, including personal information like Internet surfing habits, user logins, and bank or credit account information. Spyware can also interfere with user control of a computer by installing additional software or redirecting Web browsers. Some spyware can change computer settings, which can result in slow Internet connection speeds, un-authorized changes in browser settings, or changes to software settings. Most spyware is installed without users' knowledge, or by using deceptive tactics. Spyware may try to deceive users by bundling itself with desirable software. Other common tactics are using a Trojan horse. Some spyware authors infect a system through security holes in the Web browser or in other software. When the user navigates to a Web page controlled by the spyware author, the page contains code which attacks the browser and forces the download and installation of spyware. Click to go back |
