Spam is email sent in bulk to recipients who haven't requested it. People usually get spam from senders they don't know. Spam can be transmitted over any Internet-connected device (such as a computer, cellphone or PDA). It's a cheap way to market products or services, but it's illegal in many countries.
Nearly 70 percent of all email traffic in the world is spam. In 2007, one study showed that 90 billion spam messages are sent per day. While Internet service providers are making serious efforts to block junk (spam) email, determined spammers are making equally serious efforts to find ways to keep filling your inbox. They constantly evolve new methods of fooling the anti-spam filters.
Here is some advice about how to avoid and deal with spam:
- Understand your email provider's anti-spamming features and use their settings to flag spam or put it in a separate junk mail folder.
- Review the junk mail folder periodically to make sure legitimate email hasn't been placed there. Then delete the spam e-mails.
- Stay up-to-date on spam tactics. And when in doubt about the origin or intent of an email, delete it.
- Always have strong anti-spam, anti-virus and anti-phishing tools installed on every computer you own, set these tools to update automatically, and use settings in your email program to block spam.
