I have prepared fixed version of aswVmm: http://public.avast.com/~hnanicek/aswVmm_x64.zip
This fix is intended for 64 bit Windows only!

To apply this fix do following:

  1. Disable self defense
  2. Unpack content of aswVmm_x64.zip to Windows\System32\Drivers folder (overwrite existing files)
  3. Enable self defense
  4. Reboot

Thanks
