Agreed. The virus false positive is quite annoying. I have to re-submit to AVs for whitelisting with every new update. I'm working on getting a signature certificate which may help with it. In the meantime, those of you who have the experience to know it's a false positive, it helps if you submit to your AV. They'll scan and whitelist, and within 48 hours should have an updated virus scan to confirm the game is virus-free.
For reference, I ran ktt.exe through an online scanner and it popped up with 4 detections out of 70+ AV scanners. By contrast, a real virus will trip the majority of them:

As I mentioned, I'm just a small-time single dev at this point but I'm looking into getting a signature certification.
In the meantime, if someone wants to play but is worried about a virus - and I recommend this with any game you download from the internet - you can always run it in Windows Sandbox mode or a Virtual PC.
The game is programmed in Fusion 2.5, the same software used for games like Five Nights at Freddy's and The Escapist. As you can see, this is an issue for others as well:

Thanks for your feedback, everyone. I appreciate the patience and for those who have submitted to their AV as a false positive, an extra big thanks.
