It sounds like Panda Cloud is detecting a false positive with Zerzura. I am not familiar with this antivirus, but if you don't want to have to disable your antivirus every time you start up the game, there's probably a way to put the game on the antivirus's exclusion list so that you can just start up the game every time without problem. Someone else familiar with this antivirus would have to help explain to you how to do this, though.
