Windows 7 Professional x64

My laptop (HP ZBook 17) has started giving me this BSODs about error SYSTEM_SERVICE_EXCEPTION in netio.sys.

On Wed 27.5.2015 9:27:23 GMT your computer crashed
crash dump file: C:\Windows\Minidump\052715-10436-01.dmp
This was probably caused by the following module: netio.sys (NETIO+0x25A1D)
Bugcheck code: 0x3B (0xC0000005, 0xFFFFF880019ACA1D, 0xFFFFF8800DCFEE50, 0x0)
file path: C:\Windows\system32\drivers\netio.sys
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: Network I/O Subsystem
Bug check description: This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
I see that it is related to networking, but can someone identify from the dump what driver/software could be causing it in particular?

My laptop has
- "Intel(R) Ethernet Connection I217-LM" LAN
- "Intel(R) Centrino(R) Advanced-N 6235" WLAN
- "HP lt4112 Gobi 4G Module Network Device" 3G/4G modem

- HP Connection Manager
- Avast Free Antivirus (don't think free has a fw)
- Windows built-in firewall
- Vmware player with its virtual networking
