I guess it is still supported. 220.127.116.11 was just released
I had left it at 99% for a while but not long enough. It stays at 99% for 9 minutes then completes. (The online look-up starts at 91% and sails through to 99%) This is the same for the last version and the latest version.
I ran it once before, a few months ago and I believe it completed fine (I intend to use it regularly from now on). At the time I had NIS2010 and DSL. Now I have NIS2011 Beta and mobile broadband. Firewall component in Norton is set to Allow and I excluded it from all scans.
I am using Windows 7.
