Vista - Vista user permisssion problem

this is my first ever post, and I am an average user, so please be patient. I
have a problem with NIS2008 and Vista HB. Norton has worked on the problem
and reports it is a windows issue. I have 2 user accounts. One admin and one
standard user. Norton comes up and runs live update for the administrator.
But it will not update for the standard user. i am told this is a permissions
problem. When it tries to update the standard user the admin permisssion
window comes up. and even though I follow all the instructions (enter my
password) it does not allow me to run the live update for the standard user.
This problem did not exist using NIS 2007. I have loaded all the vista
updates as they are available. I loaded this on my other machine running
Vista Premium with no problems at all. I would really appreciate some
guidance.

Only administrators can update security software. If the admin updates it, it updates the entire computer, even the standard user. Just update from the admin account. Its nothing to worry about .
