Get a hardware or software firewall
We highly recommend all computer users have a firewall solution. There are two ways a firewall can protect your computer and network.
Hardware firewall - A hardware firewall is a physical device that is connected to your network. Often, many users who have a home network can use their network router as a firewall solution. A good example of a network security device with a firewall and other security options is the ZyXEL ZyWALL (shown right).
Software firewall - A software firewall is a software program that you install on your computer to helps protect it from unauthorized incoming and outgoing data. Keep in mind that a software firewall is only going to protect the computer on which it has been installed. Additionally, many antivirus scanners include their own version of a firewall program. See the antivirus section on this page for more information.

Other firewall programs
If you are not using the Windows firewall, a hardware firewall, or a firewall that is part of your security software you can also purchase a firewall standalone program.
Operating system and software patches and updates
There is no such thing as perfect software. Programs often have compatibility issues or vulnerabilities that can compromise your computer's security. Software patches, updates, and drivers are made available, often for free, to consumers to help keep a software program and operating systems running properly and secure.
If the program you're using does not have any method of checking for updates on its own, it is up to you to verify the program is up-to-date. Often this can be done by visiting the website of the developer who created the program. A listing of third-party companies and links to each of their pages can be found on our third-party support page.

Know how to handle e-mail
Today, e-mail is one of the most popular features on the Internet. Being able to identify threats sent through e-mail can help keep your computer and your personal information safe. Below are some of the most common threats you may encounter while using e-mail.
Attachments - Never open or run e-mail attachments from addresses with which you are not familiar. Viruses, spyware, and other malware are commonly distributed through e-mails that have attachments. For example, an e-mail may want you to open an attachment of claiming to be a funny video, when it's really a virus.
Phishing - Phishing or an e-mail phish is a message that appears to be from an official company (such as your bank) indicating you need to log onto the site to check your account settings. However, the e-mails are really sites set up to steal confidential information such as your passwords, credit card information, social security information, etc. See the phishing definition for additional information about this term as well as examples of these e-mails.
Alternative browser
Before the release of Microsoft Windows XP SP2 and Internet Explorer 7.0, Microsoft Internet Explorer was notorious for security and spyware related issues. Although it has improved since then we still highly recommend considering an alternative browser such as Mozilla's Firefox or Google's Chrome.
