Are those for sure real? In a former job, I supported system software for Windows (among other OSes), and it'd be like once a quarter that one of the antivirus companies would mistakenly flag us as malware, and since they all share signatures, the others would all flag us like a week later. It was a huge pain, because they'd kill our auto update mechanism too.
