I am looking for a way to block a specific Windows 8 app also knows as MetroApps (not common Windows program). For example let's say that I want to prevent the apps Maps and Photos from accessing the internet. I seems that Eset puts all Windows 8 Apps communication into WWAHost.exe, I was not able to figure out a way to select a specific W8App. There is an option to do that in the standard Windows Firewall but Eset takes over that option.
