0x19 was thrown due to a pool block header size becoming corrupt (0x20).

Malwarebytes' web access control driver calls into FwpsConstructIpHeaderForTransportPacket0 to aid in building headers for tcpip, and then we go off the rails on frame #01 when deallocating the block of pool memory because it was corrupt. Why was it corrupt? Well, it's easy to blame Malwarebytes' kernel-driver considering it's playing an active role in the stack's job.

Remove or update Malwarebytes.

Thanks for the reply! I will try disabling Malwarebytes and we'll see in a few days. It seems to be the source of all the BSOD I'm getting lately then! Again, appreciate the help and your time :).

You're welcome.

Disabling may not work as the kernel-mode driver will still be loaded, so if you crash, uninstall it instead.
