I said this in another post but I'll put it here to since I ran into the same problem. Installing an "unknown" developer program and then to have it flagged as a trojan is very unsettling. On top of that there is not much info out there about the development team so it becomes very hard to trust. If more info is put out there about what the program does and why, as well as more info about the developers, it goes a long way to help people trust the program. It is a really good painting program so I want to trust it, but these issues make me lean back towards just using Krita, even if it isn't as good.
