What is Spyware and Adware?
Spyware is deceptive, unauthorized software that covertly installs itself on your computer through vulnerabilities in the operating system and web browser or by piggybacking on other programs when you download what is claimed to be free, such as games, screen savers and music or video filesharing applications.
Once installed on your system, this virus-like software can steal personal information (including your ID) without your knowledge or permission, monitor your computer habits (such as where you shop online, the web sites you visit and how long you stay there, and the files you download), vandalize local machine data or use your machine as a platform from which to attack other computers and networks. Some spyware even allows others to store files on your computer or use your network bandwidth without your knowledge. More than simply an annoyance like spam, the malicious and proliferating invasions of spyware represent dangerous violations of personal privacy that are rapidly becoming a major security concern.
Associated with spyware is so called Adware. These unauthorized programs sneak onto your system, generate unsolicited and annoying pop-up ads (including pornographic material) or run silently in the background, collecting data about your browsing habits for transmission to remote databases. They can clutter your desktop, alter system files, slow done your browsing capabilities and severely impair your computer's performance.
Many of the companies distributing spyware and adware can claim their software is installed legitimately. They bury consent for installing their malicious programs in the small type of the documentation of the legitimate software you are downloading. If you are among those who do not read nor fully understand the license agreements and privacy statements you are signing, you may be missing the opportunity to decline the install of spyware by consenting unknowingly to being infected.

- When you attempt to decline the invitation to download, some spyware and adware may refuse to take your No for an answer. Instead of clicking Yes, close the web page by clicking the X in the corner of the window, or exit your browser and restart your internet session.
- Use the latest version of web browser software (always update).
- Configure the security setting of your web browser to medium or higher level.
- Set your browser not to allow third-party or session cookies.
- Though legitimate Web sites will not infect computers with spyware or adware, they sometimes place tiny files called cookies on your computer, that remember information.
