Norton and Windows phishing filter

This question is specific to NIS 2010   v 17.8.0.5 and IE 7

 

I know these are both older product versions but seeking some clarity from  those who know these two items

 

IE7 has the fishing filter. I notice this item is still "on" in my IE 7 browser even AFTER installing NIS 2010

 

Should NIS 2010 had turned off this IE7 feature?

 

Is it ok to leave it on after installing NIS 2010 ( I was never prompted to turn it off after NIS 2010 install)?

 

Is it just overkill or can it cause problems being on with NIS 2010 installed?

 

As  I said, I was never prompted to turn off the IE7  phishing filter after installing NIS 2010.
