Norton intenet secirity 2002 problems

I have been using norton net security along with systemworks Pro for about a year now.
Up until recently without problems.

I updated my systemworks to 2003 recently and have had problems with Net security not allowing me to log onto msn or some pages with with password access the pages will not load, I can not start a download using a webpage link without disabling the net security.

Help I’m getting pi$$ed off really fast and I can’t disable or remove the security as my kids use the computer frequently.

I don’t have any content restrictions set as my kids are still too young to goto any site except by accident through some undesirable popup. And this is the part that worries me, that some damage may be done if I forget to enable the security one day after being forced to disable to get to a page.

please help.
