NEW YORK -- Carl Icahn, who became a billionaire by shaking up undervalued companies, went public Monday with plans to rock Time Warner.

Comcast Cable is offering a set of Internet security tools to all of its 7.7 million cable modem subs for no additional charge.

The MSO is giving free access to three McAfee products: VirusScan, Personal Firewall Plus, and Privacy Service, which features parental controls that filter out inappropriate content and monitors activity to help prevent identify theft. Comcast said the package is valued at nearly $115.
