Some antiviruses are known to produce false positives for games made in Ren'Py 7.4. It's been a known issue since January of last year and while most antiviruses no longer false positive, some providers have been very, very slow to get on top of this despite samples and reports being submitted a long long time ago. My suggestion would be to use a different antivirus, because I wouldn't trust one that hadn't corrected a known false positive from more than a year ago!
Personally, I use and recommend Kaspersky. Extremely low impact on performance paired with very few false positives and one of the best catch rates around. The free version is perfectly competant and does a great job, too. And it's one of the few AV's out there that to my knowledge never even had this false positive to begin with!
