Firewalls filter Internet traffic to and from your computer to protect against malicious content, like malware or spyware. Placing firewalls at most or all Internet ports and connections can help safeguard sensitive information. You can configure firewalls in Norton Internet Security to block or allow traffic to and from various programs, based on specific criteria. Although you may have global rules set that restrict programs from accessing the Internet, you can create rules and exceptions for specific ports, programs and protocols.

Adding Programs to Program Control

Open Norton Internet Security and click the "Settings" option.

Step 2

Step 5

Examine the program's reputation and Norton's recommended access setting. Click the "Options" drop-down button and choose "Always Allow" to always allow Internet access to the program, or "Manually Configure" to create rules to control Internet access. If you choose "Manually Configure," you must follow the instructions on the pop-up wizard to configure the rule.
