Accessing older update definitions

We have Internet Security 2009, and a dial-up -- that's right dial-up! -- Internet connection. The updates are too overwhelming for our connect to download. The support team gave us the link to download the latest updates to a faster computer, then copy to CD and install, but obviously, I would like the older updates with their definitions. Is there a similar way to access older updates. I found a list of them all, but not access to them. Is that what Intelligent Updater is for? I tried to find a way to download that, but failed. Help. Remember, I'm a newby at this, which should make this all the more interesting. tjkris
