Several Windows users report that they can no longer start up normally. During the boot sequence, the boot sequence is interrupted by a BSOD (blue screen of death) pointing to aswNetSec.sys as the file responsible for a critical system failure. Some users report that they can boot in safe mode without connecting to the network. The problem is mostly with Windows 10, but is not unique to this version of Windows, as we also found it in Windows 7 and Windows 8.1.

What is the Blue Screen of Death?

The reason you’re here is probably because you encountered an annoying BSOD error. BSoD affects all Windows operating systems, and fixing them is quite a difficult task that requires a lot of patience.

Blue Screen of Death (BSOD), also known as stop error, dead screen, blue screen error or error check, is an error code on a blue background that appears on your computer screen when the system detects a critical error that is causing a system failure.

What is the cause of BSOD aswNetSec.sys?

We have investigated this particular problem by reviewing various user reports and looking at the most common fixes that were made by affected users to fix this particular bug report. In fact, this type of BSOD may run in different scenarios. Here is a list of culprits that can cause this type of critical failure:

  • The Avast file is the cause of the failure. In the vast majority of cases reported, Avast is the cause of the problem. There is a conflict with the kernel application, which causes a critical system crash. If this is the case, you can solve the problem by removing a third-party antivirus program (Avast).
  • Damage to the system file. If Avast is not responsible for the failure, BSOD is most likely caused by the main system corruption problem. If this scenario is applicable, you can perform a repair installation (direct recovery) to solve the problem.

Turn off the antivirus software

Although antivirus applications are required on every computer, it is possible that they may cause complications that will cause aswNetSec.sys to fail. This is due to conflicts between your system and the software. The most frequent attackers are McAfee, Malwarebytes, AVG and Zone Alarm.

If you think that your antivirus has something to do with a blue screen error, we recommend temporarily disabling it. You can do this by uninstalling the application:

  • Open the Start menu by clicking on the Windows icon in the lower left corner of the screen.
  • Windows Symbol
  • In the left context menu click “Settings”. It is marked with a pinion symbol.
  • You will see a new window with many system parameters. Click on Applications.
  • Stay on the default page and wait for your applications to load. This may take some time, depending on the number of applications installed on your device.
  • Use the search function to find your antivirus application.
  • Click on your antivirus application and select “Delete”.
  • Follow the on-screen instructions and reboot your computer after uninstalling is complete.

After uninstalling your antivirus application, try to use your computer regularly to see if the aswNetSec.sys error occurs again.
