hi! It’s a common problem with Renpy games unfortunately. If you got the file from here you’re safe. My Norton was giving me issues too.
Just FYI the creator of Ren'Py is aware of the issue and will be working on a way to stop that from happening. https://lemmasoft.renai.us/forums/viewtopic.php?f=8&t=61205&p=538773&hilit=troja... (But again, there is no actual trojan in the package).
