	About Norton AntiSpam
	approach to filter spam email messages from legitimate
	email messages.
	The email messages that you receive in your email
	program undergo scanning through different local
	filters of Norton AntiSpam. The local filters use
	Whitelist technique, Blacklist technique, and patented
	filtering technology to classify email messages as
	legitimate or spam. If the local filters classify an email
	message as spam, Norton AntiSpam changes the subject
	of the email message. Norton AntiSpam then sends the
	email message to your email client. If the local filters
	fail to classify the email message as spam, Norton
	AntiSpam collects information such as signature and
	URL hashes of the email message. Norton AntiSpam
	then sends this information to the Web Query filter
	for additional analysis.
	The Web Query filter analyzes the signature and URL
	hashes of the email message and then sends the
	analysis report to Norton AntiSpam. If the email
	message is identified as spam, Norton AntiSpam alters
	the subject of the email message and sends it to your
	email program. Based on predefined email rules, the
	email program then moves the email message to the
w	Junk folder or the Norton AntiSpam folder.
	Symantec recommends that you keep the Web Query
	option turned on. Turning off the Web Query option
	increases your exposure to the spam email messages
	that contain phishing or spam URLs.
