I get this error when I do pretty much anything. How do I fix this?

Best solution appears to be to uninstall Site Advisor from system and then to reinstall again from www.siteadvisor.com as noted in https://community.mcafee.com/message/203466

Also refer to http://kb.mozillazine.org/Problematic_extensions relating to McAfee Site Advisor 3.4.0 for more specific instructions.
