Symantec's Norton Internet Security computer application suite is a comprehensive computer protection program for use on personal computers on home and business networks. Norton Internet Security provides antivirus, antispyware, antiphishing, data privacy, and computer firewall services. Peer-to-peer file sharing software and some multimedia processing applications can be blocked by Norton Internet Security. If this occurs on your computer, you will need to open the respective ports these programs use in Norton Internet Security in order for them to work properly.
Step 1
Open the Norton Internet Security control panel by double-clicking the program icon in the computer's system tray or selecting it from the computer's desktop.
