I very much appreciate that edit, sorry I didn't get back asap, didn't realize you'd replied @Spooky. The files that were flagged were the .exe for launching the client itself and one of the files from the .zaros folder, I can't remember and didn't screenshot it.
I'm sure it's just something about the fact that it's a java file, I've had similar things happen before with games/mods for games but I'd never gotten the '0 day malware' warning before.
Again, I appreciate the replies and the verification that you did, I'm not very concerned about it anymore. Thank you.
