Richard's Token Database Sick PCs should be banned from the net says Microsoft 6 October 2010Last updated at 13:04 Botnets can contain millions of machines Virus-infected computers that pose a risk to other PCs should be blocked from the net, a senior researcher at software giant Microsoft suggests.

"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 said 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.

Gold and Silver from CPUs A while back, we did a little do-it-yourself salvaging of gold from motherboards (Can You Mine Gold From Old Motherboards?).
