On-going BSOD problems / Old Avast driver still showing after fresh installation

Hi,

You may recall my recent and on-going BSOD problem.

Yesterday I uninstalled and reinstalled Avast Free Antivirus, as it has been a long time since I had a fresh installation.

Today in Event Viewer:

The following boot-start or system-start driver(s) failed to load:

aswSnx

Version: 5.2
Symbolic Name: EVENT_BOOT_SYSTEM_DRIVERS_FAILED
Message: The following boot-start or system-start driver(s) failed to load: %1

Explanation
The specified drivers did not load correctly. The driver might not be in the expected location.

User Action
Do all of the following:

Verify that the drivers are configured correctly.
Verify that the computer is running the most current version of the drivers.

Version: 5.0

I believe this is related to Avast?

Please advise.
