Unfortunately there is no software that you can apply specifically to the hub.
You could install Virgin Media Security on your son's laptop and then use the Parental Control feature within Virgin Media Security to restrict you son's access. This feature can be password protected so that all changes can be locked down. The software is specific to the PC it is installed on so it would also allow you to remove the changes you have made to the super-hub which are currently preventing you from playing your facebook games.
If you don't want to install Virgin Media Security then a quick google search for 'parental control software' brings up plenty of alternatives.

Be aware that changing DNS settings on a local computer can be bypassed by anyone who is computer savvy, as most teens are. Why VM have removed the option to use alternative DNS servers on their hub, safe behind a secure hub administrator password is inexcusable.
I was also with same problem, but when i downloaded software from esafely.com, after that i feel now i am fully secured from the point view of kid internet safety. That software is currently available for Mozilla Firefox, Internet Explorer and Google Chrome search engines only.
Is there any progress with being able to specify DNS in the hubs configs or will I need to use the hub as a modem only and then buy another router that will let me use something like opendns... Thanks Mark

Hi as has already been pointed out its quite simple for savvy kids to google how to switch dns settings...our 12 yr old figured out how to get admin access in xp, recorded the screenshots & posted it on you tube! as vm seem unable to allow parents to properly keep their kids safe online by enabling dns settings in the hub we're considering switching to a provider who takes these concerns more seriously...
