I think the antiphising is a nuisance on NIS2009. As it intereferes with login's on forums and music sites i am a member of.
Even if i turn it off, it gives me the "FIX NOW" crap. I think Norton doesn't approve many sites. Well this doesn't get my approval.
Only way to get round this, is to browse with firefox, in IE NIS2009 even blocks legits websites.
Get your act together Norton, and stop being paranoid. Antiphising is a paranoia device, the way i see it.
The older versions of NPF and NAV didn't do this.
