HomeSafe - on Business service too?

So I've recently noticed the nefarious TalkTalk Virus Scanning engine following me around, treading on private URLs without permission and generally going some way to confirming a few predictions made by a certain Mr Orwell. I'm actually a Pipex customer, but Pipex has been rolled into TalkTalk -- however I believe Pipex customers were sort of lumped into the retail division of the mothership.

Anyway - what I'd like to know is this: is the HomeSafe product operating on on the business service offered by TalkTalk? I don't just mean is it activated, but is it doing any scanning?
