The minimum hardware devices and software applications that are currently needed by any individual or company that connects a PC to the Internet:

  1. Hardware firewall to make your systems invisible to "port scans" by hackers;
  2. Software firewall to prevent worms from sneaking in or communicating out via your Internet connection;
  3. Antivirus program to detect and eliminate infected files and e-mail attachments;
  4. Antispam filter to prevent obviously bogus e-mail messages from reaching your Inbox and tempting you to click links to crooked Web sites;
  5. Anti-adware scanner to delete adware, spyware, and browser hijackers in your system and prevent them from getting control in the future.
  6. Update-management software to handle today's constant stream of patches and upgrades, whether the choice is Windows Update for individuals or a small-business or corporate package to handle 5 to 50,000 PCs.
