Having taken advantage of the CB/ McAfee deal, and set up the audits, I received within hours a message from my hosts saying that my domain's CPU usage had greatly exceeded the limit. It looks as if I shall not be able to use this resource; although it did reveal [among many others] an issue with CB registers page; 'Web Application Cross Site Scripting': [details available]
Regarding the overload: you can set a slower scanning speed in the McAfee device configuration panel. Ask McAfee support for help if needed, they are there to help you. I haven't seen any overload on our servers due to their scanning, as the default scanning speed corresponds to approximately 2 persons browsing the site on a properly configured server.
Regarding the error on your CB registration page, please Private-Message me the details, I didn't detect any such issues in our scanning.
