I was just looking in my outpost firewall settings and it it set to normal, it also said backround and disabled. What would happen if it was set to load on the backround settings?

Did you check the Help File?

There are three startup modes:

• Normal (loads Outpost Firewall automatically at boot-up and displays its icon in the System Tray).
  
• Background (Outpost Firewall will run in invisible mode, without its system tray icon or any of its dialog windows).
  
• Disable (Outpost Firewall will not run automatically at startup).
  
  Note
  Background mode is provided for two reasons: to save system resources and for a parent or Systems Administrator to block unwanted traffic or content in a way that's completely hidden from a user.
