I have uninstalled McAfee 7.0 because I was having too many problems connecting to the internet. Three McAfee Firewall Netork Miniports are still listed in the device manager under network adapter with the yellow exclamation mark. I have tried everything I can think of and am unable to unistall these adapters. The message always says Failed to unistall the device. The device may be required to boot up the computer. How do I get rid of these?????
