Site Advisor is a service that reports on the safety of web sites by crawling the web and testing the sites it finds for malware and spam. McAfee shows small site rating icons. These alert you to potentially risky sites and help you find safer alternatives. These site ratings are based on tests conducted by McAfee using an army of computers that look for all kinds of threats. The Site Advisor doesn’t collect any personally identifiable information.

The result is a guide to Web safety.

- SAFE: Very low or no risk issues.

- CAUTION: Minor risk issues.

- WARNING: Serious risk issues.

- UNKNOWN: Not yet rated. Use caution.
