Over the past few days I've had constant blue screens of death with bdfndisf6.sys being pointed out as the problem.
I've uploaded my Minidump folder and the BDSP thing here, shout if you need anything else, I really need this fixed
(Won't let me edit the post...)
Just happened again, .dmp file http://forum.bitdefender.com/index.php?showtopic=56151
You need a few more posts before the post edit function is enabled.
It would be a good idea to send the dump link and full details to Bitdefender via e-mail just in case this gets missed.
