My Bitdefender 2016 TotalSec output an alert because of maleware in the exe. On virustotal three additional Programms detect maleware.
I am surem there isn't any maleware, but you should check this mishits.
lol I have asked Renpytom, the developer of the engine, more than once... It seems that for passing all the virtual signatures he would need to pay a considerable fee, and since it's a free program he isn't going to pay for it.
Perhaps now that he's started a Patreon, we can ask for it to be done, once he reaches a moderate monthly income. I will certainly suggest it, because that security pop-up is really annoying!
