Method 1: Uninstalling 3rd party antivirus (if applicable)
As it turns out, the number one cause why this issue is occurring is due to a problematic Avast driver that ends up conflicting with some kernel files used dooring the booting sequence. Unfortunately, if you encounter this issue, the only way you’re going to resolve the issue is likely by getting rid of the 3rd party security scanner and moving towards the built-in antivirus (Windows Defender).

If you’re ready to get rid of your 3rd party antivirus, follow the steps below to boot in Safe Mode and uninstall the 3rd party antivirus suite completely (without leaving behind any remnant files): If the same BSOD crash is still occurring, move down to the next method below.
Method 2: Performing a Repair install
If the method above didn’t allow you to resolve the issue, chances are the issue is occurring due to some underlying system file corruption that will not go away so easily. In this case, chances are you will be able to stop the aswNetSec.sys BSODs by resetting every WIndows component along with all booting data. The most popular way of doing this is with a clean install. But this procedure is quite destructive since it will make you lose all your data including applications, games and personal media (photos, videos, audio files, etc.). A better and more efficient way is to do a repair install. This will reset all Windows components and boot data while allowing you to preserve your files, applications, and games.
