The Outpost have boot protection.
Another thing: the Outpost have the option to import/export configurations, and if I import the configuration that comes when we install the firewall, the Network Shield stops to show this "DCOM Exploit attack" warning, so I think that we can conclude that could be a program that I gave permissions...
This also could be a bug in Network Shield...
It's possible, in the future, that Network Shield say what program give access to the Network Shield blocks that attack?
