According to the kernel extension list you have also installed the AVG antivirus and its network shield:

  121    0 0xffffff7f81b0c000 0x4000     0x4000     com.avg.netshield.kext (1.1) <4 1>

This will not work. Having installed two antiviruses at the same time is always a bad idea as there will most probably be interferences between them (as you could see :slight_smile: ). If you remove AVG, the webshield should start working correctly.
