When you get some time... Look here:

Update Services installation issues

If your windows update is pointing to your local WSUS, then you must include
the Windows Defender in synchronization setting.
In Products selection, please include Windows Defender
In Update classifications, please include Definition Updates
How to use Windows Server Update Services (WSUS) to deploy definition
updates to computers that are running Windows Defender
http://support.microsoft.com/kb/919772
You must synchronize the server and approve the definition for clients to
get the latest definition.
Your IT dept/Admin must permit and publish WDs definitions from the internal
corporate WSUS server.
So talk/mail him/them and ask for permission.
I'm sorry I don't have any better advice to offer.
Let us know maybe someone else can conjure up something else to try.
