BSOD shortly after system boot, IRQL_NOT_LESS_OR_EQUAL

Hello, I've recently had a BSOD with the IRQL_NOT_LESS_OR_EQUAL error. I've had this BSOD a couple of times in the past, but after I rebooted it was alright. However today every time, shortly after I log in on Windows, this BSOD pops up. I've attached the BSOD report. Thanks for your help

Please remove Norton.

Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability compared to other internet security software. Malwarebytes is a great combo to MSE. They are free and lightweight.

Also uninstall your existing Antivirus software before you install MSE.

Good and Free system security combination.
