Assuming that you have set the auto forward in your Virgin Media webmail account (rather than in an email app or client) have you checked that the slider in the webmail auto forward settings box is on (green)?
Also, just to clarify, the auto forward in VM webmail only works on new emails as they arrive in your VM Inbox. So it will not auto forward any emails that are already in the inbox or any new emails that VM sends straight to your VM Spam folder.
