McAfee SiteAdvisor

McAfee built a system of automated testers which continually patrol the Web to browse sites, download files, and enter information on sign-up forms.

With this information they can tell you:

• E-mail practices of the website
• They rate sites based on both how much e-mail they send as well as how the e-mail received looks. Does it look like spam or not?
• Downloads
• SiteAdvisor checks the impact of the site's downloadable software.
• Does the software on the site have any viruses?
• Online Affiliations
• Does the site try to redirect you to a site that may cause harm to your clients?
• Is your site a "feeder" site?
• If your site has links to too many suspicious sites, it will be flagged.
• Annoyances
• Does this site use a lot of pop-ups?
• Does this site request to change the user's home page or favorites list?
• Does it try to use 3rd party tracking cookies?
• Exploits
• Does this site threaten the security of the user’s machine?
• Is there software on the site that may be dangerous to a user?
• Is the website trying to use a browser's security vulnerability to install software

McAfee also allows users to add comment and reviews for a site.

There is also a plug-in for Firefox available.
