Key Points

  • Any computer that’s connected to the Internet is at risk from a variety of sources, including hackers and viruses.

  • The best defense against viruses is to install antivirus software and make sure to update it regularly.

  • If you receive an e-mail message warning you of a new virus, it might be a hoax. Check it out before you forward the message.

  • If you’re concerned about viruses that piggyback along with e-mail messages, configure Outlook Express to block potentially dangerous file attachments.

  • Spam, also known as unsolicited commercial e-mail, is difficult to stop, but you can make a dent in the problem by using filters with your e-mail program.

  • Windows XP includes a powerful personal firewall program, Internet Connection Firewall (ICF), which can stop hackers from breaking into your computer.

  • Cookies are generally helpful files that make the Web easier to use, but they can pose some privacy risks.

  • Internet Explorer 6 includes tools that you can use to reduce the risk to your privacy from cookies.
