Google Safe Browsing is a service provided by Google that provides lists of URLs for web resources that contain malware or phishing content. The Google Chrome, Apple Safari and Mozilla Firefox web browsers use the lists from the Google Safe Browsing service for checking pages against potential threats.

To use the tool, just append a URL to the end of http://www.google.com/safebrowsing/diagnostic?site=

For exapmple:
http://www.google.com/safebrowsing/diagnostic?site=http://hostonnet.com/

Google will then return four sets of security information about that page as follows:

• The current listing status of a site and also information on how often a site or parts of it were listed in the past.
• The last time Google analyzed the page, when it was last malicious, what kind of malware google encountered and so fourth.
• Did the site facilitated the distribution of malicious software in the past?
• Has the site has hosted malicious software in the past?
