We switched our ISP to a Net Neutrality ISP and I needed to replace the provided McAfee. I did a lot of research and came up with this configuration for our older laptop. I've been very happy with this set-up and had only a slight learning curve with TinyWall and VoodooShield. Sophos has been very easy to live with but has developed a slight bug lately - incorrect Last Scan Date reporting. All clean so far!
