A plan by Microsoft Security Chief Scott Charney would place infected or unsecured PCs in an Internet isolation ward. And block users from Internet access.

How might this work? Let’s try this potential scenario.

Hello this is your ISP. We regret to inform you that your system has been quarantined and will not be allowed to access the Internet. We have detected that your system may be infected with malware and that you are not running the approved and certified security software to protect your system. Please remove the malware and update your security software (how you can do this without an Internet connection is your problem). Sorry about any important emails, business opportunities, emergency notices and VOIP-based phone calls that you are now missing. Have a nice day.

Could you imagine getting a message like this from your ISP? Well, if Charney’s plan goes into effect, your computers could be subject to quarantines and being locked out from Internet access.
