I tried Avast when I installed Windows 8 and suffered from a few BSOD's myself, then I shifted to AVG 2013 but a few people were saying it wasn't that great and that Defender was good enough. I have not had any problems with Defender and because it's based on Microsoft Security Essentials (which has always been good) personally I think it's fine and no better or worse than any of the others. This is a matter of choice of course, if you want to use AVG 2013 go ahead but if you're finding that it's causing BSOD's then un-install it and use something else.
The driver reference table provide links to the update driver site where possible. In some cases there will not be a windows 8 version available yet in which case you should un-install/remove it if at all possible, sometimes windows 8 will use its built-in drivers, if not then try and make sure you're using the latest windows 7 drivers for the hardware.
For your convenience I will link to the site which might contain updated win8 drivers for the hardware I listed above, it's worth saying though that if you're not getting BSOD's after un-installing Avast then these update might not be needed:
Rt630x64.sys:
Realtek
Accelerometer.sys & hpdskflt.sys
- Unable to find updated drivers for windows 8, might consider un-installing if it's not needed by following this article:
