Virus alert when I try to open MapleRoyals.exe

I've played MSRoyals last year, but i've stopped to focus on university, btw.
Today I decided to return to play , but after download the game and try to start it , this following error message appeared:

Spoiler: Error

Translation:
"Could not complete the operation successfully because the file contains a virus or potentially unwanted software."

The problem would be AVAST? No, i don't have AVAST on PC. Would be Firewall? No, I've turn it off when installed the game.
I don't know what I need to do for solve this, and I really want to play MSRoyals, again. ;c

 

You have an antivirus program and whatever program you use is the problem.

 

No, I assure that I have not .

 

So you get a virus alert without having any antivirus software, that's not possible.

 

I'm trying to undestand this too. I never install a antivirus just to get rid off this kind of problem.

 

You likely have windows defender since you can't uninstall it.

 

I don't remember the Windows Defender. Now you said, I checked and he was active, as default . Deactivated and reinstalled MSRoyals and this time it worked!

 

Make Sure you make an exception for the mapleroyals file. So you can have your windows defender active and play mapleroyals at the same time
