I'm one of those people that needs a bit of protection from their selves at work, so I wanted to add facebook.com to my hosts file. But something strange happens. The moment I add it Microsoft Security Essentials notifies me of a PossibleHostsFileHijack and presto: the facebook entry is removed automagically! All other entries, like gmail et cetera, are working just fine and dandy, but everytime I try to add facebook, it gets removed!
What is this voodoo? Any ideas? I'm on a windows 7 professional 64bit machine, but the same happens at home on my 32 bit windows 7 machine. Any ideas? Facebook being evil?
