Hi, After SP1, when I try to update my Virus definition file, I get the following error : "Only Administrators are permitted to perform this action. Please ask your System Adminitrator log in and perform the action." I am the user with Administator privileges on my machine. I even logged in a the administrator and tried to update the Virus definition file. I get the same error. I even checked the User Accounts and veruified that I have the Administrator privileges. I am in the "Administrator" group. How can I resolve this? Thanks Hans
