When running BlackFog alongside Kaspersky it is important that you are running the latest version of Kaspersky greater than 19. Older versions have a memory handling bug which manifests over time and eventually causes Windows to crash. Kaspersky drivers in v19 seem to be the main cause of the problem and are documented on the Kaspersky support site.
