A firewall is only one line of defense against Internet criminals. To ensure the information on your computer is secure, make sure you have virus-protection and data encryption software installed, and keep your security patches updated.

Antivirus software

Virus-protection software is an important step in keeping your computer free of viruses. This software runs on your computer continuously to provide protection against viruses, Trojan horses, worms, and other nasty codes that could corrupt and destroy your valuable data.

Security patches

Also make sure to get critical software patches from Windows Update to keep your PC safe. Use Automatic Updates in Windows XP to install all the available patches you need. For more information, read on Microsoft's website.

Encryption software

Encryption software adds additional protection for your data, making it more difficult for the contents to be accessed should it be intercepted.

Protection starts with you

Security patches, antivirus and data encryption software can help safeguard your PC, but the most important protector of your computer is you. Never give system passwords to those you don't know and trust.
