Phil at 360Radar has replied to a contact from me and with his prior permission I quote his e-mail here:
Thanks for your email.
As you say, Avast is still warning (incorrectly) that there is an issue with the Airport-Data.com site. Since AVG and Avast are the same product with different interfaces but the same backend that will too.
It's because both products take URLs from publicly available lists of supposedly dodgy sites. Nothing wrong with that per se, but they don't check that there's an issue or not. They simply push them out and trigger loads of false alerts ...
I'd recommend getting a decent antivirus product like Norton or McAfee which have the resources to check the URLs and don't just regurgitate someones data.
This will save us all contacting him.
On this basis I will create an exception for the website in Avast. Everything else is working on my PC, and whilst a little bit whiny, Avast Free scores well in tests.
I've also reported a false positive to Avast. Probably a waste of time...
