Comcast offers the Norton Security Suite for free with an XFINITY Internet subscription, as of 2015. Account holders can get the suite by using the Comcast ID or email address and password associated with the account.
All other security software must be uninstalled from the computer prior to installing the Norton Security Suite. Comcast offers customer support representatives to assist with any questions when downloading or using the software. Customers can download the software by clicking on the link found on the Comcast website under Constantguard. The software suite protects against viruses, spam and social media dangers. It can also restore lost PC horsepower and show all the devices connected to a home network.
