Moving preexisting definitions from one machine to another. NIS 2009

I live in the magical world of dialup. Its a world were it takes hours, even days to update an new installation of pretty much everything. To save a lot of time, I would like to copy my completely up-to-date installation of Norton Internet Security 2009 from one machine to another.  I would like to locate the Live Updates cache and copy it to a flash drive, and then copy the files to the same location on the target machine, but I have been unable to locate the cache to even attempt this feat.

 

Can anyone help me?  Re-downloading all of these files isn't an option for me.
