Comcast, the nation’s largest residential Internet service provider, announced last week that it is expanding an initiative to contact customers whose PCs appear to be infected with a malicious bot program.
The Philadelphia-based cable Internet company is expanding nationwide a pilot program that began in Denver last year, which automatically informs affected customers with an e-mail urging them to visit the company’s security page. The system also sends the customer’s browser a so-called “service notice,” a semi-transparent banner that overlays a portion of whatever page is being displayed in the user’s Web browser.
