Can't connect ot server to update virus definitions

I am receiving a message at the bottom right of my screen saying my virus definitions are out of date. When I hit the update the process stops at ‘can’t connect to servers’. Strangely, when I open the software it says everything is up to date and functioning.

I have just installed Windows 10 though I think this was happening prior.

Can anyone help?

Thanks
