But that's another story. For the time being, my internet access has been restored (hence this message!). Watch this space....
Thanks for the comments. I'm still at a loss to know how NTL knows which PC infected messages are coming from if the IP changes every time I dial up. And if they really have a way of identifying the infected PC, why do they tell me that they have detected an infection in my PC when there pretty evidently isn't one? Is puzzlement.

My guess would be that they can match your MAC address to your customer details, in which case you should not have been walled.
If they just wall the IP address (despite it being returned to the pool and re-leased) then there is a problem with the way they identify compromised machines.
Or it could be that the IP was walled while it was leased by the spammer, who then released it and was picked up by you with the restrictions still in place.
I'm guessing.
Perhaps someone who really knows how it works will post a reply.
