After starting up my old desktop I was surprised to see a BSOD with cmdguard.sys at fault. The blue screen occurred just after logging on to windows, about the time when the desktop widget and Comodo symbol show up in the tray.
The blue screen did not reoccur after the subsequent reboot, so I’m, not sure how reproducible this will be, but my system is set to do a full memory dump. I’ve compressed it but its still larger then the allowed attachment size.
