Function
In addition to actively crawling and analyzing web sites, Norton Safe Web relies on feedback from users and Norton Community participants. When a drive-by download occurs at a web site, the suspicious URL is automatically reported to Norton Safe Web for analysis. The reported site is rated as unsafe if the analysis confirms that the download is malicious.
To ensure that its site rating accurately reflects the current state of a site, Norton Safe Web performs frequent re-analysis of Web sites. Norton Safe Web employs a site rating aging algorithm which estimates how often the safety of a particular Web site will change. Some of the factors used in this analysis include the site's rating history, the site's reputation and associations, the number and types of threats detected on the site, the number of submissions received from Norton clients, and site traffic. In other words, unsafe sites that are more likely to have been cleaned up are re-analyzed often while those that might take longer to remove detected threats are re-analyzed less frequently. User reviews are also accepted, with contributors ranked by reputation. Should a site owner dispute the ranking of their site, they can submit a request for re-evaluation after completing a validation process.

Famous quotes containing the word function:
“Every boy was supposed to come into the world equipped with a father whose prime function was to be our father and show us how to be men. He can escape us, but we can never escape him. Present or absent, dead or alive, real or imagined, our father is the main man in our masculinity.”
—Frank Pittman (20th century)
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
“To look backward for a while is to refresh the eye, to restore it, and to render it the more fit for its prime function of looking forward.”
—Margaret Fairless Barber (1869–1901)
