Hi Biell and welcome to Sevenforums! :)

Your BSOD is caused by BitDefender so I would recommend that you uninstall it and install MSE:
Microsoft Security Essentials - Microsoft Windows

Cheers /Boris :)

Yes a tool that I'm using said that the crash was probably caused by a dll that is of BitDefender.

Also it is a known troublemaker.

Biell Gates, you need to clean up your system of cracks.
You also need to update your system, you are running Windows 7 while others are using Windows 7 with service pack installed.
OS Version:                6.1.7600 N/A Build 7600
Until you have cleaned your system of cracks no support may be given.
