SiteAdvisor software is an award-winning, free browser plug-in that gives safety advice about Websites before you click on a risky site. With SiteAdvisor software installed, your browser will look a little different than before. We add small site rating icons to your search results as well as a browser button and optional search box. Together, these alert you to potentially risky sites and help you find safer alternatives.

Site ratings are based on information gathered from visits to websites using test computers. We test for a comprehensive set of security threats including e-mail practices, downloads, browser exploits, phishing, e-commerce vulnerabilities, website annoyances, and links (online affiliations).

SiteAdvisor software is free, easy to install and even easier to use. And it doesn't collect any personally identifiable information.
