    BSOD on boot, ntoskrnl.exe


    Recently, I have been having random BSODs on booting after the Windows 7 boot animation. There have been 4 different types of BSOD, those being SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, BAD_POOL_CALLER, BAD_POOL_HEADER, and DRIVER_CORRUPTED_EXPOOL. Looking at BlueScreenView, they were all related to ntoskrnl.exe. I have attached my SF log for examination.

    Thank you very much.

    It seems to be a combined effect of COMODO Firewall Pro Sandbox Driver and avast! Virtualization Driver.

    A known situation. It happens.

    Uninstall Comodo. Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
    Download, install and update those, and then run full system scans with both of them, one by one.

    Let us know how it is running now.
