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 These types of avgSnx.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg.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:

avgSnx.sys could not be found.
avgSnx.sys failed to load.
The file avgSnx.sys is missing or corrupt.
Windows failed to start - avgSnx.sys.

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: avgSnx.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (avgSnx.sys).

It's Critical to Resolve Blue Screen of Death Errors
