I think the BSOD is caused by my Bitdefender. I would be so frustrated if that is case and I would have to uninstall Bitdefender as I spent money on the antivirus and I really like it.

Hi, my apologies, I was sleeping and just woke up! Yes, you can disable verifier.

As you guessed in your original post, verifier is flagging bdfwfpf.sys (Bit Defender - more specifically the firewall, I believe) as the culprit. Please uninstall Bit Defender for temporary troubleshooting purposes and replace with Microsoft Security Essentials.
