Norton Internet Security on EEEPC 901 (fills C drive)

My 2nd PC licenced for Norton Internet Security, is an EEEPC 901. This has an SSD C drive of only 4GB.

Norton Internet Security installed fine (I specified D drive), and worked OK for a few weeks, but for the last few weeks its been reporting "out of date". This is because it cant run LiveUpdate, because the C drive has been filled up with what I presume are new virus definition downloads.

 

I have run the EEEPC recommended utilities that try to move things from C to D drive. But these dont move "c:\Documents and settings/All Users" folder. Unfortunately this is where I assume Norton puta its LiveUpdate downloads.

Currently there is 1.3 GB under c:\documents and settings\All Users\Application Data\Norton

 

Question: Is there some setting I can change that will change this location from C to D, so Norton stops filling the C drive?
