Symantec 9.0 - Updated via executable file

Created: 20 Apr 2011 | 3 comments


We're still using some NT4 Servers inside our company, but from now, we're trying to do all the update of our last NT4 servers without a management server, so i'm downloading every sunday the last virusdefinitions, and updating our servers with this defs file ...

All our NT4 clients are installed as unmanaged client, and there's not a problem at all until we're doing an update ... From there, I've always a 'Warning' popup box, that says :

Symantec Antivirus Corporate Edition

Symantec AntiVirus Auto-Protect failed to load.

It becomes boring to try to protect our server against virus infection, with this problem ... We also know that there's no support anymore for NT4, and or SAV9 (version .... But don't really understand why were'nt able to update that product without problems !  (I can see that the update went fine, because i can see the scan engine update, as the virus definition file inside my management console on the local server)  but it's impossible to have our auto-protect loaded from there ...

So if anyone as any suggestion to help me with this, that would be very nice !

We've already a Symantec Endpoint Protection 11.1 server installed (but the 9.0 client aren't manageable via this server :-s That's why i'm trying to install SAV9.0 unmanaged clients on my NT4 servers ;-) )

Thanks to all !!!!

SAV 9 is way outdated, your systems are not getting the protection from modern threats using a product that old. On top of that, you are running OS's that are no longer supported by Microsoft. You really need to get all your systems up-to-date ASAP.

There has been an Antivirus (AV) Engine Update posted 10 May 2010. Since this update, some legacy versions of SAV, namely 7.x, 8.x and 9.x are likely to be affected by the above symptoms. Due to the additional features added to the definition set, this would show an increase in size of the definition file. Because of this, it will affect old systems and some EOL products that may not work properly.

Migrate to the latest supported Symantec security product, currently Symantec AntiVirus (SAV) 10.1.x or Symantec Endpoint Protection (SEP) 11.0.x

Issues such as no definition updates or non running scans with end-of-life (EOL) products - SAV 7.x, SAV 8.x and SAV 9.x

Symantec Antivirus 9.x will reach its End of Standard Support as of March 31, 2009. Virus definition updates for version 9.x will be discontinued on April 1, 2009. Please contact your account manager or reseller for information about our current shipping versions.

As you may know, i completely agree with you that i must update those systems, but as far as i know, it's impossible for me to update those systems to a newer OS without broking a lot of things, they're all old DB systems and it's only compliant in windows NT4 ( they should become obsolete in a year of two!).  But in the meantime, i must manage those like others systems in my company...

I've tried also to update the SAV9.x to SAV10.x but this last version requires at least windows 2000, all my other systems (windows 2003, 2008) are completely updated with SEP11 ...

So i was trying to figure it out to have those update working correctly on that systems, but without updating my OS, broking a lot of things in our DB's, it seems impossible at this time !

Thanks for your reply, and your time.

Kind regards.
