How do I keep my protection updated?
To some degree, Norton AntiSpam updates itself by
learning from your outgoing email messages and other
data. However, to receive up-to-date copies of Symantec
spam definitions, you must subscribe to this service. You
can then choose to have these definitions updated
automatically.
Why do I need a subscription to spam
definitions?
Though the product is self-training, local spam
definitions are developed only by the criteria you input
and from the sample of email messages you process.
Symantec spam definitions are developed from a much
larger set of information and can prevent you from
seeing many of the more common types of spam.
Why does so much spam include clusters of
meaningless characters?
These and other unusual elements in spam are intended
to confuse spam filters that look for keywords.
