Нашел решение для локальной сети, где все клиентские машинки будут обновляться с сервера, который тянет обновления с инета. Это программка Mirror.

What is a mirror?

By default, avast! updates are performed using the Internet. When an update is initiated, the program setup (responsible for installation, updating, changing, and deinstallation) connects to a randomly selected server of our company.
It "asks" whether any new updates are available; if there are some new files, it proceeds with downloading and installing the files (update). The process is the same both for virus database and program update.

If we take the content of our update servers and store it on a computer (preferably a server) inside a company network, we create a mirror - an image of our server. This is called mirroring.

What is the point? Having only a mirror itself is not very useful - but if we manage to make avast! use the mirror to perform the updates, the situation changes. The advantages of this approach are described in the following chapter.

Advantages of mirroring

Mirroring is useful especially in large computer networks. The main advantages of this solution are:
- Speed
The time needed to deliver the update files within a company network will always be shorter than downloading the files from Internet servers for every workstation.
- Reliability
You administer the mirror yourself. Your server (mirror) will be available to the workstations even if our update servers are inaccessible.
- Security
When avast! updates are handled using the mirror, it is not necessary to install/permit the HTTP protocol (or Internet at all).
- Lower traffic
Since the workstations don't have to connect to the Internet to update avast!, the load of your Internet connection will decrease (and subsequently, the load of your proxy server).
