Comcast guarding users helps protect all of us

Comcast announced 'Constant Guard', an initiative to detect customers' botnet-infected PCs using aggregated data (e.g., Spamhaus lists and behavioral detection), show in-browser service notices with weekly reminders and email confirmations, and provide remediation tools (McAfee suite and a Comcast toolbar). The report frames this as a large ISP-led effort to reduce botnet-driven spam, DDoS and click-fraud and encourage other ISPs to adopt similar protections.
