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[1] first introduced at CodeCon on February 10, 2006,[2] and later acquired by McAfee[3] 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, but can now also be accessed through a downloadable Browser Plugin.[4][citation needed]

SiteAdvisor LIVE

A paid version of McAfee SiteAdvisor, McAfee SiteAdvisor LIVE, is included in McAfee Total Protection and has extra features:

  • Download Protection - SiteAdvisor LIVE allows the consumer to adjust how aggressive SiteAdvisor scans downloads. This can stop downloads which are considered to be slightly, probably or possibly risky depending on setting determined by the user. This feature can also be turned off.
  • Protected Mode - Allows the user to set a password for SiteAdvisor to prevent users from accessing or downloading from Yellow and Red rated websites. This password will also be required to change any SiteAdvisor settings after Protected Mode has been enabled.

In addition to selling to the end consumers, McAfee also sells to the web site owners with their McAfee Secure program. --

Total Exposure

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.

Extra features of McAfee SiteAdvisor

  • Rates email and IM links
  • Indicates sites potentially harmful to your computer
  • Allows users to safely shorten URLs when sharing links
  • Alerts users to possible phishing and identity theft scams
  • Redirects you away from red and yellow sites (if Protected Mode is enabled).


False positives

SiteAdvisor has received criticism for incorrectly flagging web sites with a caution or warning label.[5][6][7]

False negatives

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,[8] meaning a Green rating may not be up to date and may provide a false sense of security.

Communication and accountability

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.[9] 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.[10]

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.

The software design makes it difficult to turn SiteAdvisor off and McAfee keeps changing the method of doing so. The program reinstalls if a customer updates McAfee's Total Protection package.

McAfee Secure

This program 'certifies' a web site so that it can show the McAfee certified logo, and also get a GREEN rating beside search results (according to their marketing materials).


McAfee SiteAdvisor now makes use of the TrustedSource website reputation organisation, to act as something like a 'cloud' intelligence software to get the most up-to-date information on websites as possible, very similar to McAfee's Active Protection (Artemis) system.[citation needed] The details of this system are not known.
