Hi everyone, nexTGen here.
I did everything I could to solve the problem.
I started by uninstalling renpy and installing it again and then I scanned it with antivirus.
Then, I scanned all the renpy files and content, all the models and absolutely everything related to renpy with 360 TS: https://ibb.co/M6fQJkX
After that, I bought Avast and rescan, as well, all the renpy files, models and content: https://ibb.co/PZXGggr
After that I recreated the distribution of the game, and I scanned it archived: https://ibb.co/vckcQ7p
Then I unzipped it and scanned it unzipped: https://ibb.co/YW5L6BN
After that, I scanned most of the files with Jotti: https://ibb.co/pntyMbh
That's about all I could do, the game looks completely clean.
I'll probably re-upload the game tomorrow.
Thank you all for your patience.
See you soon.
