Additional Information

Adware are programs that secretly gather personal information through the Internet and relay it back to another computer. This is done by tracking browsing habits, generally for advertising purposes.

Adware is a type of program that displays an advertisement of some sort. Adware is usually related to a specific Web site that is cached in the Web browser. In some cases, it changes the home page of your Web browser to point to a specific Web site. Because adware is not malicious in nature, it is not considered a virus.
