I'm having regular BSOD (BAD_POOL_CALLER) on my main computer since end of Jan 2018. I'm running Malwarebytes Premium 3.4.5 (the problem started on an earlier version) and Bitdefender Total Security 2018, and if I recall correctly both programs had medium updates just before the problem started.
Bug Check Code : 0x000000c2
Crash Address : ntoskrnl.exe+1640e0
Caused By Driver : fwpkclnt.sys

File Description : FWP/IPsec Kernel-Mode API
While Malwarebytes is not mentioned in the logs I found out that
- the problem only occurs when a second or third computer (both running Malwarebytes free without live protection & Bitdefender 2018) is connected to my network while Malwarebytes Premium is active on my main computer with all four protection modes enabled. It appears that Malwarebytes Premium tries to scan the other computers and then hangs (other comps are fine).
- the BSOD never happens when Malwarebytes is completely shut down on my main computer
- I cannot solve the problem by adding my other network computers to Malwarebytes exclusions, because my main comp will always freeze before reaching that point.
If it's not a Malwarebyes-only problem, my guess is that it might be a compatibility issue between MBAM's llive protection and Bitdefender. I've had these issues in 2016 and solved them by adding the following MBAW exclusions to Bitdefender recommended in this forum (plus new exe's contained in later versions):
