Support XFINITY Internet About Constant Guard


In our ongoing effort to improve your XFINITY Internet experience and satisfaction, we have simplified and streamlined your security offerings. The Constant Guard Protection Suite and Mobile app password management services will no longer be supported and managed by Comcast.

We are pleased to offer you similar great features and functionality through the comprehensive Norton Security Suite, which is available to all XFINITY Internet customers at no additional cost. If you prefer, you can still use your existing Constant Guard Protection Suite services with Fast Connect through White Sky, an experienced technology company, at no additional cost.

Comcast Malware Scan

Malware is software that's installed on your computer without your knowledge or consent. Malware is used to take control of your interactions with the computer. To protect yourself from unwanted malware, simply download and install the XFINITY Toolbar, as an Anti-Malware tool is automatically included. The Anti-Malware tool allows you to schedule scans automatically or run a scan at any time in an effort to help you protect your computer.

Comcast Anti-Malware Application Updates

The new version of the Comcast Anti-Malware application automatically pushes the new malware DAT file update to your computer, which keeps you protected from new versions of malware. The malware DAT files are generally updated each business day (Monday-Friday); however, if your computer is not connected to the Internet, you may miss a DAT file update. If you do miss a DAT file update, the application will provide you with a red warning indicator in the summary tab. The warning indicator will allow you to manually update the DAT file.
