The McAfee SiteAdvisor, later renamed as the McAfee WebAdvisor, is a service that reports on the safety of web sites by crawling the web and testing the sites it finds for malware and spam. The service was originally developed by SiteAdvisor, Inc, an MIT startup first introduced at CodeCon on February 10, 2006 and later acquired by McAfee on April 5, 2006. Since its founding, it has received criticism for its improper rating of some sites, and more importantly the length of time it takes to resolve complaints.
Prior to mid-October, 2014, the functionality of SiteAdvisor could be accessed by submitting a URL to the website at https://www.siteadvisor.com/sites/, but can now also be accessed through a downloadable Browser Plugin.
A paid version of McAfee SiteAdvisor, McAfee SiteAdvisor LIVE, is included in McAfee Total Protection and has extra features:
In addition to selling to the end consumers, McAfee also sells to the web site owners with their McAfee Secure program. --
As of Dec 2010, McAfee Secure marketing materials say there are 350 million installs of McAfee SiteAdvisor, and a likely much larger viewer base with search engine agreements such as that with Yahoo.
SiteAdvisor has received criticism for incorrectly flagging web sites with a caution or warning label.
The very nature of SiteAdvisor and the long periods between site crawls mean that even if the SiteAdvisor tests were 100% accurate a Green rating offers no guarantee of safety. Malicious code and browser exploits often spread fast over large numbers of websites, meaning a Green rating may not be up to date and may provide a false sense of security.
In the event of a positive result website owners are not contacted. Although a dispute resolution service does exist, the final decision rests with McAfee. In the event that a perceived threat is removed from a site the site's rating will return to Green as the data ages. Depending on the nature of the threat this process can take from 10 days to a year after the site is re-crawled, no strict timetable is provided.
Yahoo, who uses the McAfee SiteAdvisor rating in their search results, does not get the rating change for another 4 weeks. It is unclear if rating changes in either direction take this long, or only corrections (RED to GREEN). Yellow is rarely, if ever, used.
