I have Windows 7: Home Premium. I ran a McAfee scan and there was nothing wrong, but it said my firewall was turned off. I went into the control panel to turn it back on but an error message popped up. "Windows Firewall can't change some of your settings.
Error code 0x80070424" How do I turn it back on? Is my computer infected?
