Each day, McAfee visits Websites and tests them for a comprehensive set of security threats. From annoying pop-ups to back door Trojans that can steal your identity, they find the danger zones before you stumble on them. The test computers look for  downloadable files like screensavers, toolbars and file sharing programs which may be bundled with adware, spyware, viruses and other malicious computer code. They also examine browser exploits, e-mail, phishing, e-commerce, pop-ups and cookies and affiliations with other sites.

McAfee uses proprietary techniques to visit and test sites  and to analyse data.  The results are presented to the users in the form of colored icons.

• green : very low or no risk issues found
• yellow : minor risk issues found
