Bitdefender
With the most recent update to the Plarium browser, Bitdefender has flagged both your browser and the Sparta game as malware and immediately removes the .exe files to run them.
Is there a fix for this? Have fallen back on the google chrome browser but won't be able to use that for much longer since they will stop supporting flash.

We did some improvements with Plarium Play last week including the one about the security alerts from different antivirus programs. Looks like you've updated your app and the issue stopped.
