NAV 2004 would slow my web browsing down at some sites, like Ebay, but not have a problem with simple sites. I finally found the problem listed at the NAV site. They say they don't know what causes it, have no fix, but if you disable the scanning of Javascript (.js) the problem goes away. What garbage this program has become. They no longer test it before releasing it. Peter Norton should demand his name be removed from this POS.
