Right, so in this dump, Norton is fully removed yet the cause of the crash remains the same - Realtek RTLxxxxx Wireless USB 2.0 Adapter driver. With this said, it's apparent that the driver itself is indeed the problem as opposed to Norton (please don't reinstall Norton now, but after we've solved your BSOD's).

We can see the driver itself is dated from 2013, not too old. However, it still may be incompatible with Windows 8.1 despite its date.
Your next step is to either check for an update from - Realtek
or uninstall the software/driver and remove the adapter entirely for troubleshooting purposes. If crashes stop, the adapter's device drivers are unfortunately incompatible, and you'll need to find an alternative.
If however you continue to crash, there's two things I want to take care of:

Your Waytek keyboard drivers are nearly 7
years old, no good. Either remove the keyboard and its software from the picture entirely, or uninstall the software, shut down
(not restart), unplug the keyboard, allow Windows to boot, and when you come to the login screen, plug the keyboard in. Hopefully Windows Update won't attempt to download seven year old drivers, and instead the generic Windows keyboard drivers will install. If it does however install old drivers again, do the following:
- Click Start, right-click Computer, and then click Properties.
- In the Tasks list, click Advanced System Settings.
- On the System Properties dialog box, click the Hardware tab, and then click Windows Update Driver Settings.
- Select Never check for drivers when I connect a device.
- Click OK twice, and then close the System dialog box.
and then repeat the uninstall, shut down, etc method.
In your loaded drivers list, dtsoftbus01.sys
is listed which is the Daemon Tools driver. Daemon Tools is a very popular cause of BSOD's in 7/8 based systems. Please uninstall Daemon Tools. Alternative imaging programs are: MagicISO, Power ISO, etc.
