Aaah, what makes you think XP won't be safe on the internet? Are you succumbing to the Microsoft hype so they can push you to Windows 7/8 ? XP will be just as safe today as it will be in 1 year on the internet. There should be no reason to remove its internet access if you have all the latest updates.
Because the anti virus folks tell me my XP PC is not protected now. They will not provide new installs for XP machines - I tried several 'free' AV programs and none of them would install.
