How to Get Free Antivirus Protection with Comcastby eHow Contributor ; Updated September 28, 2017
Comcast provides the Constant Guard Protection Suite to its Internet customers. The Constant Guard program includes protection from online threats such as malicious websites, phishing schemes and other methods used to steal your information. It also includes functions to secure your information while browsing. Firewall and antivirus services are provided by the Norton Security Suite bundled with the program.
Remove any other virus protection programs from your computer before you get started. Two different virus programs on your computer will compete for control and cause errors. Use the uninstaller included with the antivirus program or the "Add/Remove Programs" utility in the Windows Control Panel.
Call Comcast tech support (800-COMCAST) if you have never used your Comcast email. After verifying your account information the tech support representative will provide your email address.
Go to the Comcast.net website and click the "Security" link in the top right corner of the page. Click "Get It Now" in the main window. Scroll down and click "Install" to continue.
Click the "Continue" button if it appears. Log in using your Comcast email address and password. Follow the wizard that appears to download the installation program.
Run the installation program after the download finishes if it does not run automatically. Norton Antivirus runs automatically after installation.
Clicking the "Register" button in the "Email" tab of the Comcast.net website lets you set up your own email address without calling tech support.
Previously Comcast offered McAfee Virus protection for free. If you downloaded McAfee you can switch to Norton and as part of the download McAfee is removed from your Computer.
