I am running brand new windows 10 Pro on Dell Precision Workstation. Had a different similar Dell which I returned to get upgraded power supply and bluetooth in and it gave me identical BSOD. Using Avast free and only keep on basic protections. Running malwarebytes at the same time. Put exceptions into both programs to prevent conflicts. Have been running this on another computer which uses identical programs without issue. Kept getting ndu.sys BSOD. When I uninstalled newest version of Avast, problem stopped. I had also turned off Fast User Switching, as recommended in other forums for ndu.sys BSOD. I will reinstall Avast free and see if issue persists. I will turn off Ransomeware protection on Avast since I have it on premium malwarebytes. BTW, I excepted the ransomeware conflict in Avast and malwarebytes before.
