Hi Steve
It's not the URL it is complaining of, rather
On Windows, Norton Internet Security virus checks all downloads. One of 
the names they give to the result of their scanning is 'File Insight'. 
 From what I can tell, it uses a few checks:
- virus scanning using known signatures
- observable malicious behaviour
- how well known or used it is across other users of Nortons.
It seems that the last of these is a causing the warning.
Obviously this is not a problem for me, but may be concerning for less 
tech savvy Windows users that get the warning.
There isn't a way within Nortons to 'report for clearance' of the file. 
And my chat with a (entry level) Norton representative got nowhere.
I'll email screen captures in the next email. Let me know if they don't 
come through and I'll paste them somewhere.
Let me know if I can give any more information.
