Learn more about Norton AntiSpam

Norton AntiSpam lets you categorize the email messages that you receive in your email programs into spam email and legitimate email. It filters legitimate email into the Inbox folder and spam email into the Junk folder or the Norton AntiSpam folder.

The Norton AntiSpam local filters use Whitelist technique, Blacklist technique, and patented filtering technology to classify email messages as spam or legitimate. For these filters to work efficiently, Norton AntiSpam requires antispam definition updates at regular intervals through LiveUpdate. These updates contain signature information of spam and legitimate email messages. The updates also contain any new rule that Norton creates to filter spam email messages.

Norton AntiSpam uses enterprise-class, spam-filtering technology to classify the spam email messages from legitimate email messages. Norton AntiSpam uses a real-time filter delivery mechanism and filters email messages using various local filters at different levels. The local filters classify the email messages as spam or legitimate. If the local filters classify the email message as legitimate, Norton AntiSpam collects information such as signature and URL hashes of the email message. Norton AntiSpam then sends this information to the Norton web server for additional analysis.

When the email message is classified as spam, Norton AntiSpam changes the subject of the email message and sends it to your email client. The email client identifies the change in the subject of the email message and moves it to the Junk folder or the Norton AntiSpam folder.

Norton AntiSpam uses predefined email rules and the user-defined Allowed List and Blocked List, to expedite the scanning of email. It accepts email messages from the list of allowed email senders and blocks email messages from the list of blocked email senders.

Norton AntiSpam also automatically imports the lists of addresses from supported email programs during the initial integration. It helps you keep your list of allowed and blocked email senders in sync with your current address books. When Norton AntiSpam imports the addresses from your Outlook address book or Windows address book, it also imports the addresses that are available in the Safe Sender and the Blocked Sender lists.

Turning off Norton AntiSpam increases your exposure to receive unsolicited email messages. Always ensure that Norton AntiSpam is turned on. It secures your email client from unwanted online content.

Import of Safe Sender and the Blocked Sender lists are not supported on Microsoft Outlook 2010 or later.

You can review all the antispam statistics under the AntiSpam category in the Security History window.

When you open your email client, the welcome screen appears. If you do not want the welcome screen to appear in the future, check the Don't show this again option before you click Close.

Norton AntiSpam adds a drop-down list or a few options to the toolbar of supported email programs.

You can use the following options:
