avgnsx.exe - Application Error

AVG Internet Security
Program Version 8.5.441
Current Virus Database Version 271.1.1/3079

Were are starting to randomly get avgnsx.exe errors, resulting in all browsers not being able to load any web page.  I have tried the following, each as a individual effort to resolve this error, yet the error persists on some PCs and not on other PCs.

Clean the registry
Disable Link Scanner
Disable Safe Web Search Add-On
Remove Dump Files (Suggested by Support)
Re-Install of Internet Explorer & Fresh Install of AVG
Combofix.exe
Clear Cache from all Browsers


After the error appears, only a reboot will resolve the issue.  Sometimes it resolves it for a couple of hours, sometimes it resolves it for days, and sometimes it resolves it for what seems like permanently.  I have found no common denominator on these machines -

Error is happening on PCs with Windows XP & is happening to less than .2% of the machines on our network.

Download the AVG un-installer from their site and restart, then install the latest version 9

Understood an I appreciate the suggestion, but I have over 20,000 client at over 50 sites, managed by the AVG Management Console.  The Console will need to be updated - SQL Database will be converted during Version Update and then the update will need to be pushed out over the network, via the AVG Proxy Servers.

This would have to be place on the Change Request as a Project.  I need more of a global solution, as well as figuring out the root cause of this error.  I am growing concerned it may become a very big problem.  Anny further suggestions would be greatly appreciated.

Thanks

Yes, I spoke with AVG Support and they Web-Ex'd in and could not find a cause for the error.  They suggested the upgrade to 9.0 as well, but at the moment this is not an acceptable solution.  It may be an acceptable solution in about 2 weeks time.  I just need to be prepared with a solution in the events this becomes wide spread.

I have forwarded the Diagnostic files to support for review.   Still waiting to hear back.
(Ran Diagnostic Tool on 3 PCs with reoccurring avgnsx.exe error, and ran Diag Tool on PC not receiving the error.)

0x0A4B7000 refers to Java, and it would appear you are not the only one with this issue

May be worth looking at the Java versions and doing a test with java removed from system and IE

UK_Andy,

Your replies have been gretaly appreciated and I am in the stages of testing the latest Java update on several of our problem machines.  In a network of 23,000 - 25,000 PCs you can understand how many various versions of Java we have out there.  After 1 more continued week of testing the new java update in concerns to the AVGNSX.EXE errrors, I will reply back and award points.  

Thanks Again,
TG_Tech

Hi
I to have done a few tests on VPC's as I have AVG 7, 8, 8.5 and 9.  I have found that several issues appear depending on the version of Java and other IE plugins. I also noticed the only time I had no problems was when the plugins where on or just after the same release date as the AVG.
I hope this helps and you are able to resolve your issue.
Another point would be, looking at getting a level playing field in regards to your systems e.g. WSUS, OS
I really wish you all the best and sympathise with regards to the amount of systems you have to manage...
