How can I fix the aswNetSec.sys BSoD error?

The "aswNetSec.sys" BSOD (Blue Screen of Death) error is related to Avast antivirus software. It occurs when there is an issue with the Avast network security driver (aswNetSec.sys). To fix this error, you can follow these steps:

  1. Boot into Safe Mode: If you are experiencing frequent BSODs and cannot access your computer normally, try booting into Safe Mode. Safe Mode allows you to start your computer with minimal drivers and services, which can help identify if the issue is caused by third-party software like Avast.

    a. Restart your computer. b. During the boot process, repeatedly press the "F8" key until the Advanced Boot Options menu appears. c. Select "Safe Mode" from the list using the arrow keys and press Enter.

  2. Uninstall Avast: The first step is to uninstall Avast completely from your system. While in Safe Mode or if you can access your desktop without encountering the BSOD, follow these steps:

    a. Press the Windows key + R to open the Run dialog box. b. Type "appwiz.cpl" and press Enter. This will open the Programs and Features window. c. Locate "Avast" in the list of installed programs, right-click on it, and select "Uninstall."

  3. Use Avast Uninstall Utility: Sometimes, standard uninstallation may not remove all Avast components. In such cases, you can use the official Avast Uninstall Utility to ensure a clean removal.

    a. Download the Avast Uninstall Utility from Avast's official website. b. Boot your computer into Safe Mode. c. Run the Avast Uninstall Utility and follow the on-screen instructions to remove Avast completely.

  4. Update or Reinstall Avast: After completely removing Avast, you can try updating it to the latest version or reinstalling it. Make sure to download the latest version directly from the official Avast website.

  5. Check for System File Corruption: Sometimes, system file corruption can cause BSOD errors. Run the System File Checker (SFC) tool to scan and repair corrupted system files:

    a. Open Command Prompt as an administrator. b. Type the following command and press Enter:

    sfc /scannow

    c. Wait for the scan to complete and follow any on-screen instructions.

  6. Update Drivers: Ensure that your system's drivers are up to date, especially the network drivers. Outdated or incompatible drivers can cause conflicts leading to BSOD errors.

  7. Check for Malware: Perform a full system scan with your antivirus software to check for malware infections that may be causing the error.

  8. Use Windows Restore Point: If the BSOD error started occurring after a recent software installation or update, you can try using a Windows Restore Point to revert your system to a state before the issue appeared.
