If you are worried about viruses making their way onto your computer, or about your children's safety while they're browsing the Internet, installing a robust security suite on your computer might help alleviate those fears. Fortunately, if you are an XFINITY subscriber, which is Comcast's new brand name for its cable division, you do not even have to pay a dime to protect your computer from such threats. Included in your XFINITY subscription is a license to download and use the latest version of Norton Security Suite, which you can install from the company's website.
Uninstall any anti-virus or security suite currently installed on your computer.
Open your Internet browser and visit the "Protection for PC" page on XFINITY's website (link in Resources). Click on the "Get It Now" button.
Enter your Comcast.net email and password and click on "Sign In."
Click on "Start Download." Once your computer has finished downloading the file, double-click on it to run it and start installing Norton Security Suite. At this point, if you have previously installed the free version of the McAfee security suite that XFINITY used to provide to its customers, the Norton installer will automatically uninstall that program and restart your computer.
Select "OK" and click on "Agree and Install" after reading the terms and conditions. Norton Security Suite will now install itself on your computer.
Alternatively, you can also download the full Constant Guard suite from XFINITY, which automatically includes the full version of Norton Security Suite, along with other applications such as Family Sense and Identity Guard.
