AutobouquetsMaker has nothing to do with EPG even for cable/sat, ABM updates the channel frequencies etc.
Make sure Cable is not selected in AutobouquetsMaker -> Providers and select Freeview and green button to save. Now if Providers Order appears in the ABM menu check it and make sure Virmin/Cable is not in the list, if it is then you will need to go back to tuner config and set the tuner back to DVB-C, then in ABM->Providers disable virgin/cable, and then go back to tuner config and set the tuner back to dvb-T2
I had an issue before where I disabled sat tuner but hadn't disabled sky in ABM but as the tuner was disabled sky wasn't listed as an option but it was still selected (hidden) so still tried scanning it.
I don't know if its the same thing but might be worth checking
