Could someone please clarify that that this is a snakeoil issue but not a security issue/virus. I guess we don't want people to delete gamefiles because of some antivirus/snakeoil bullshit alert.
Antivirus software is a threat for your system, don't use it. There have been many examples where broken AV software was used to infiltrate systems. It doesn't help, you are not "safer", all it does is opening new attack vectors. It gives you a feeling of security which is very dangerous. People tend to open malicious email attachements or download weird suspicious files bc "the AV will guard them" while they don't if they don't use bullshit AV software.
I would state the exact same if this file was actually malicious and the alert legit. The web and any file is a risk but using AV software is not a solution at all. Even Microsoft, one of the biggest software companies with a huge amount of really talented programmers was not able to make their WindowsDefender secure.

Think of this if you think that trusting one of those shady snakeoil companies is a good idea. It isn't.
