How to Update Virus Definition in Unmanage Client

Hi to all.

I have 1 computer out of my domain.

I had already install Unmanage Endpoint protection 12.1 RU6 MP6

The point is: How can i perform an update (The specific computer has Internet) in the virus definition without the user do anything?

I had install the Live Update Version 3.3 but when i run the Luall they show me a pop up screen.

I prefer if it is possible to add the update in scedule so i will be absolutely sure that the computer will update the virus definition every day.

Thanks and regards.
