Downloading NOD32 update modules

Hello,

I used to install Avast for my clients who does not have internet on the network then teach them how to download the update module each couple of days from a separate PC connected to the internet to install on each of the other PCs.

Avast is not really doing the job.. I mean, I am going on testing myself different antivirus and I ended up using CA and NOD32.

CA needs a internet connected PC to work after installing and rebooting; NOD32 works fine after installing and rebooting.

I browsed NOD32 website but I can't find separte update module offered for download (similar to what Avast provides); did I miss something on their website or is it a service NOD32 does not provide and which I am seeking in vain?

Thanx
