Illegal warning message from Virgin

I have plugged a kryptview box in my wall and it somehow allows me to view all the channels. However on one or two of the channels there is a warning from Virgin saying this box is illegal and should not be attched to the cable???
Is it possible for them to detect where along the wire this box is as I have also inadvertently unplugged the Virgin one?

 

use a splitter and keep your virgin box plugged in as this has talkback so virgin knows if this box is in use as for the kryptview just delete those channels with illegal warnings virgin cannot detect these boxes as they dont talkback

 

Just wondering if the box can't talk back why would you need to delete the channels that give the warning?

 

you dont have to delete them.but if you dont want to see them on your channel list then delete them

 

I have a eurovox max V.

Virgin is completely unplugged - would they have any idea what i am receiving?

 

OK that makes sense!
