Ok I want to purchase and install another copy of TDS 3 for my client but he is not totally computer literate. Therefore I was wondering does TDS-3 has an unattended signature update script? i.e. each time I boot the system the TDS-3 will contact the DCS servers and update or TDS-3 will periodically contact the DCS servers in order to check for an update (every day or every few hours). That feature is very important for him, since he does not want to be bothered with updates, he wants a kind of set-it-and-forget-it AT system.
