Hello,
I have been having exactly the same issue. I was having it with both V2 (+Anti-Exploit) and V3. I have attached my minidumps that both blame 'tcpip.sys' however the memory dump blames 'mwac.sys' for the same crashes. I also seem to feel it has something to do with skype and web browsers (because when it happens it happened within the first 30 seconds of me starting my PC or when starting Firefox/Edge). It seems quite inconsitant as to if it happens, however it has happend at least 10 times in the last month and is more prone if I quickly start to do things on the PC after startup.
I have included 2 minidumps and the 'WhoCrashed' description of the memory dump (its 1Gb). If you want this let me know.
On Sat 10/12/2016 08:27:10 your computer crashed
crash dump file: C:\WINDOWS\memory.dmp
This was probably caused by the following module: mwac.sys (mwac+0x6BF3)
Bugcheck code: 0x19 (0x20, 0xFFFF9483DDBA7830, 0xFFFF9483DDBA7850, 0x4020015)
Error: BAD_POOL_HEADER
file path: C:\WINDOWS\system32\drivers\mwac.sys

Sadly I have clean installed MalwareBytes (using mbam-clean) to try and solve the issue prior to finding this thread. If I see more crashes after the clean install I will add them here.
Kind regrads
