The McAfee Site Advisor Internet protector is a useful addition to the suite of protection. The powerful analysis tools are constantly locating and testing new sites, analyzing the likelihood of spam if you enter your email address and downloading the files for analysis. The McAfee system adds color coding to your search results to tell you if a site is likely to be unsafe. We think the ability to block only the malicious content in an otherwise safe site is particularly useful, as it means you can see safe sites that may have been hacked. However, the software is not so good at detecting phishing sites, which don’t hang around long enough to be tested.
