Have an iMac G5 won't stay connect to the internet by cable/ethernet for more than minute or so. After I reboot the Verizon modem I have five green lights, ethernet, network settings, isp, internet server all green. Open browser, internet, server go red. Somehow my grand-daughter downloaded some program that gives me a world back ground "Not licensed evaluation use only". If I change the background the world background comes right back.
