Download problem

Hi, I try to download the standard Norton security.  When the process comes to 99%, it stops and a message mentions an error.  There is also no possibility to get in connection with the Norton server. I also tried to use the Norton Tools to tempt first to erase a virus, but the download does not work.  When I try to send a report of error, I receive a message tolding me that  it is not possible because there is no personal identification. What can I do? I know that I already have a virus "ransom". Thanks a lot.
