  1. 1

    Protect your computer against viruses and spyware. These are typically sent through e-mail or your browser. Viruses can cause tons of damage to stored data. They can delete files and provide others access to your computer. Be sure to install a quality antivirus/anti-spyware program onto your computer.

  2. 2

    If your computer is always connected to the Internet via a broadband connection, be sure to set up a firewall. This will stop outsiders from seeing data on your computer.

  3. 3

    Keep your software updated. Install security updates as soon as possible. This will help to protect you from new viruses and spyware programs.

  4. 4

    Use passwords whenever possible. Use a password that combines numbers and letters.

  5. 5

    Log off your computer when you are not actually using it.

  6. 6

    If you have particularly important or sensitive files stored on your computer, protect these individual files. Use an encryption program to protect these files and limit access to these files with passwords.

  7. 7

    Back up important data that is stored on your computer. Get into the habit of copying important files. You can copy files to a CD, DVD or an external hard drive.

Tips and warnings

  • A firewall is included with most Windows operating systems.
  • You can use the encrypting system in Windows to protect sensitive files.
  • Do not open e-mail attachments unless you completely trust the sender. This is a common way that viruses are transmitted.
