Fo3nix has pointed you in the right direction. This problem is Nortons big failing.Really deep hooks into your system registry are always an issue with Norton stuff..Getting rid of all the remaining "crud" left by Symantec is recommended as I have known these remnants to upset ZoneAlarm in some instances.!! The link fo3nix has provided should help..but knowing Norton...there might be some hooks left in your registry. If you are not familiar with editing the registry...leave well alone..it's a dangerous place to fiddle around in if you don't know what you are doing. See how things go after following the advice fo3nix gave you and if you have need of further help...post again ...Ed
