Is it turned on in your Windows 10 installation? What?! I think that switch is off by default. Yes, that's right, even though I am using Norton 360 there is a switch to turn on periodic Defender Antivirus scanner scans in parallel to Norton 360. But it got me thinking, what other components of Windows Defender are still running? Take a look at the second image. Well, soon after rebooting the PC I had two notifications from Windows Defender Firewall that it had blocked applications, one of which was JRiver Media Center 23! See the first image. Windows Defender Firewall should not be blocking applications under those conditions. It just gives more control of Defender.Īnyway, with the firewall reset I turned Norton 360 back on and rebooted my PC. This is actually a Management Console and allows Group Policy changes.
Most were not active, but I found a "Restore Default Policy" link in the "Windows Defender Firewall with Advanced Security" App that I have installed. To do so I turned off Norton 360 and tried the reset functions is various parts of Windows. This made it a bit of a challenge to reset the Windows Defender Firewall without completely uninstalling Norton 360, but I managed. All security is managed by Norton, including all security settings. So I do not rely on any of the Windows Defender functionality. I also run Norton 360 Antivirus and Firewall, which includes Antimalware.
Note that I am running Windows 10 Pro with the latest updates available in Australia (version 10.9 Build 16299 / version 1709 installed Dec 15, 2017, with patches up to January 10th). I don't even use ICS, but I do have Hyper-V Manager installed, and it needs the ICS service to connect to the internet from a VM. I had to reset the Windows Defender Firewall today to fix a problem created with the "Internet Connection Sharing" service by one of Microsoft's recent updates.
