Even if reevaluation request is submitted, the site will still be listed as "unsafe" and no reevaluation action is taken place indeed. Norton Safe Web is complained about by many users/web administrators as websites will be classified as "unsafe" incorrectly. Should a site owner dispute the ranking of their site, they can submit a request for re-evaluation after completing a validation process. User reviews are also accepted, with contributors ranked by reputation. 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. 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. Norton Safe Web employs a site rating aging algorithm which estimates how often the safety of a particular Web site will change. To ensure that its site rating accurately reflects the current state of a site, Norton Safe Web performs frequent re-analysis of Web sites. The reported site is rated as unsafe if the analysis confirms that the download is malicious. When a drive-by download occurs at a web site, the suspicious URL is automatically reported to Norton Safe Web for analysis.
In addition to actively crawling and analyzing web sites, Norton Safe Web relies on feedback from users and Norton Community participants. Norton Safe Web differentiating Google web searches as safe (green) and unsafe web search (red)
