BSOD on new SSD

[afikbar]

Hello all,
I've recently installed new SSD to my pc. connected it via SATA to my mobo. switched in bios to AHCI, and installed fresh OS on it.. I was told that way it will automaticly will install the AHCI Drivers. anyhow the Drives are listed as SCSI devices, after some failures of changing it, i gave up since the benchmarks are really good.
That was the background. Since the installation i've got 2 times BSOD with the following error:
IRQL GT ZERO AT SYSTEM SERVICE

is it related?
I'll attach the debug zip.
Thanks for the helpers

Hello,
Thank you for your reply,
I've Uninstalled BitDefender. how long should it pass before it safe to say that was the problem?
