AvgSnx.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with avgSnx.sys. Most of the issues concerning SYS files involve Blue Screen of Death (BSOD) errors. These types of avgSnx.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. AVG Internet Security update) issues. Some of these errors include:

STOP 0×0000007A: KERNEL DATA INPAGE (avgSnx.sys)
STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (avgSnx.sys)

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter avgSnx.sys BSOD errors after you've installed new hardware, software (AVG Internet Security), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to avgSnx.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a avgSnx.sys Blue Screen of Death error after recent changes.

How to Fix avgSnx.sys Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your avgSnx.sys issue. These troubleshooting steps are listed in the recommended order of execution.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many avgSnx.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the avgSnx.sys error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your avgSnx.sys File (Caution: Advanced)

Download avgSnx.sys Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying avgSnx.sys to your appropriate Windows system directory. AVG Technologies typically does not release AVG Internet Security SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing avgSnx.sys and all other SYS files for AVG Internet Security. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
