You don't say whether you have Virgin's Cable or ADSL (via phone line) broadband.
If it is the Cable service, then you must use a Cable Modem provided by them and these days they are supplying a combined Modem and Router in the form of the Superhub. What you can do though is set it in "Modem only" mode and connect your own separate router to it. I have one of these Cable Superhubs and its WiFi performance is not particularly good.
With ADSL via the phone line, you should be able to connect your own combined "Router and ADSL Modem" to the phone line.
