Symantec signature updates are not signed

I am currently unable to update our symantec endpoint AV applications due to the fact that the symantec update executables are not signed by symantec and the applciation won't run the update without validating the symantec signature.

As it turns out Symantec is now requiring that thier updates be signed and that the host machine have updated (through Microsofts update services) root certificate entries ( with symantec included).   One the host mahcine's root certificates are updated then the new av update can be validated againt the root certificate.
Try an Alternate Method!
...& Update virus definition files using the Intelligent Updater!
(But first make Sure that you have the latest Application Version!)

Go to the updates page for new virus definitions.

Depending on your version of Windows, do one of the following:
For Windows XP or Windows Vista 32-bit or Windows 7 32-bit:

Click the first file in the list under Filename. The file name starts with the year and ends with v5i32.exe. e.g. 20120618-017-v5i32.exe
For Windows Vista 64-bit or Windows 7 64-bit:

Go to the 64-bit Platforms section, and click the first file in the list under Filename. The file name starts with the year and ends with v5i64.exe. e.g. 20120618-017-v5i64.exe
Save the file to the Windows desktop.
On the desktop, double-click the file that you saved.

Thank you for your input - i have in fact attempted to use the inteligent updater from multiple sources and they have all been rejected by the platforms we currently have running.  I appears that there has been a transistion point in how Symantec provides thier AV updates and i missed a migration task.  Your reference to the lastest engine is probably on target, I'll try reloading the lastest version of the AV suite and see what that yields.
