Hi Wroot,
That file does not seem to be malicious in itself. It's not capable of causing any harm.
It does have a "bad" reputation with SEP 12.1's reputation-based technologies. If using SEP 12.1 with SONAR / Download Insight, it should be detected.
What would be very useful would be to get the installer and .exe's for the original FakeAV itself, before you managed to uninstall it. No doubt that will be encountered and submitted to Symantec by someone in due course, and protection added with traditional AV signatures.
Hope this helps!
