How to Disable McAfee Site Advisor
SiteAdvisor is a McAfee security component that installs on your web browser. Once installed, the security tool alerts you of websites that carry dangerous tools such as Trojans, viruses and spyware so that you do not have to visit them. McAfee SiteAdvisor uses a rating system to create awareness of dangerous websites. You may want to disable SiteAdvisor if the program is damaged and causing browsing errors, or if you are simply using a different security tool that performs the same or similar functions.
