BBC: Scott Charney of Microsoft's Trusted Computing team, is advocating for a public health approach to dealing with computer viruses. He recommends "quarantining" infected PCs in order to prevent them from being used as botnets. "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," he wrote in a blog post. "In the physical world, international, national, and local health organisations identify, track and control the spread of disease which can include, where necessary, quarantining people to avoid the infection of others."
Charney says a computer should have to provide a "health certificate" showing that it has security measures in place before its user can connect to the Internet.
