To date I have not found a satisfactory solution. CA Internet Security Suite would let my game connect to all servers, but caused severe page loading lag at Newegg and some other sites. It also gave me frequent disconnects from the internet that required a system reboot to correct.

The McAfee Security Suite that was pre-installed on this computer would do well in all other areas but would stop my game server loading at 65%.

After totally uninstalling both of these I tried installing JUST Avast and using the Vista (premium) Firewall. Game server stopped loading at 65%. Finally, I uninstalled Avast and Installed AVG and just using Vista Firewall and my gaming server loads to 100% and web page loading speed is excellent. I tried the PC Tools Firewall with AVG, but again experienced the gaming server stopping at 65%. I am not truly happy with AVG/Vista Firewall security solution, but I suppose I will have to accept it for now.
