Norton Intelligence Updater

I have the 2014 version of Norton Internet Security, and I keep getting notified by the software about fixing the software with over 200 MB of updates through the Live Updates feature.  I called Norton three times and chatted with them on the Norton website once, and was told to download a file from the Norton Intelligence Updater page, that there would be an icon showing up once installed.  But I was notified that the files downloaded were corrupt, and to do the download over. Therefore, no icon showed up on my computer desktop.  Also, I was told that the IU was to be used for downloading anti-virus updates, that, once installed, I don't have to download 200 MB of updates any more on a dial-up connection.  I mentioned that my Windows XP computer is a 32-bit machine, that 94 MB out of 331 MB were downloaded for the IU.  Now, on the day that I'm typing this, I was told that I can take a blank CD-Rom disk and take it to a library to download the IU file to the disk and transfer it to my computer.  I think this sounds good, and will try this very soon.  What do you think?  Do you agree with my information, or what experiences did you have with Intelligence Updater?  I would like to hear from you.  Thank you very much for reading my message.
