The standard phishing detection that comes with IE7 really does slow things down when it comes to navigating web pages. In contrast, the option offered as part of Norton 360 is much faster. So much so that you hardly notice that it’s there at all. When I restored IE7 on my PC and ran it for the first time, Norton asked me to be its default fraud detection and I was away from there. Norton 360 offers nothing for Firefox, my preferred and default option but there may be plug-ins that address that need.
