Okay, technically, this is not a bug, but I wasn't sure where else to post this...

Title says it all - I've got Kaspersky Internet Security [Version 18.0.0.405(i)] and it happened to me twice now that it deleted (completely, without asking me) Spine. It happens as soon as I try to export a PNG sequence - I guess it sees Spine writing so many images onto the drive as suspicious.
I haven't managed it yet to set en exception for Spine, maybe I've done it wrong, but it deleted the program although I thought I had Spine in the list of programs it should trust?

Best,
Momo
