bit defender is picking half the files up as malicious. when I looked it up, it seems it does not like whatever software the game runs on. It deletes so many files the game shows as uninstalled in the itch.io app. Is identified as "atc4.detection"
Antivirus software often flag indie games as having malware/viruses because they haven't been downloaded many times and so are considered untrustworthy. The VN itself is perfectly fine. The best thing to do would be to mark the game as an exception in your antivirus program so you can play it. If you don't want to do that then e-mail me privately at email@example.com so we can sort something out.
