Microsoft Wants Isolation Ward for Infected PCs

Microsoft security chief Scott Charney wants to protect your computer from botnet-infected PCs on the Internet. In a paper published yesterday, Charney proposed issuing “health certificates” to malware-free machines, requiring antivirus updates for those with vulnerabilities, and quarantining PCs infected by botnets. In a post to a company blog, he argued, “Just as when an individual who is not vaccinated puts others’ health at risk, computers that are not protected or have been compromised with a bot put others at risk and pose a greater threat to society.”
