2 On the Personal Firewall menu, select a level. Your options are:

Blocks many ports that are used by harmful programs. However, it can also block useful programs when they use the same ports.

Disables Norton Personal Firewall and allows all Internet communications.

2On the Java Applet Security or ActiveX Control Security menu, select a level. Your options are:

High

Medium

None

Blocks your browser from running any Java applets or ActiveX controls over the Internet. This is the safest, but most inconvenient, option. Some Web sites might not operate properly using this setting.

Prompts you when Java applets and ActiveX controls are encountered. This lets you temporarily or permanently allow or block each Java applet or ActiveX control that you encounter. It can be bothersome to respond every time that you encounter a Java applet or ActiveX control, but it lets you decide which ones to run.

Lets Java applets and ActiveX controls run whenever you encounter them.
