Here is a detailed guide on how to solve this problem, if you have windows 10 and windows defender or another antivirus is tagging the game client as a virus, a false positive, here is how to solve it:

This solution is the same for all antiviruses, if you don't know how to add an exception on your antivirus simply Google "my_antivirus_name how to add file exception".

 

Step 0 - Notification (Optional)

Allow the file as pictured once you see a virus report notification and click on it

Step 1 - Add a folder exception to your game folder

Windows Defender -> Virus & Threat Protection -> Virus & Threat Protection Settings -> Exclusions

Your default game folder location should be c:\Users\Your User\AppData\Local\ There select the game folder Celestia Luna Online and add it to exclusions.

 

Step 2 - Turn off real time protection

Same location Windows Defender -> Virus & Threat Protection -> Virus & Threat Protection Settings

Step 3 - Reinstall

Now it's time to reinstall the game, because of how windows defender works it won't restore the file even if you try.

After reinstalling you must patch fully before continuing to the next step!

 

Step 3 - Add a file exception

Located in your game folder you will find a file called LUNAClient.exe, add this file to exceptions.

Now you should have the following exceptions listed:

Final Step - Re-enable real time protection

And lastly enable real time protection back on and enjoy playing!

Also occurred to me last night (as an Avast user). Just in case you use Avast like me:

1. Turn off Avast's behavior shield temporarily (protection > turn-off the behavior shield)

2. Reinstall the game

3. Add celestia luna installation directory to exclusion (settings > general > exclusions > add > browse the directory)

4. Re-enable Avast's behavior shield

5. Enjoy your game

 

It will probably happen with any other antiviruses (AV). The AV will detect CL as a malware, then the AV will immediately delete the game executable or move it to the virus vault. Generally for any AV, just disable the real-time protection, reinstall the game, add the game to exclusion, and finally re-enable the real-time protection.

Geez... These AV detection heuristics are so terribly programmed that false positives are everywhere.
