Problem might be that whoever is clicking restore is likely running that software as an admin thereby the user clicking restore is the admin user. I'm not 100% sure though, but I think that's the behavior.
Edit:
Found this[0] to clarify what happens when you run software as UAC. I can imagine an A/V program needs admin privileges to run altogether.
