Comcast Spyware Scan

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

Comcast Anti-Spyware Application Updates

The new version of the Comcast Anti-Spyware application automatically pushes the new spyware DAT file update to your computer, which keeps you protected from new versions of spyware software. The spyware 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.
