Optimize Internet Explorer 8's Performance.
While this Internet Explorer 8 feature is commendable, it also brings down browsing speed.
Smart Screen Filter provides protection from phishing sites.
It checks each and every Website that you visit and analyzes them for any suspicious features or activities.
This task is done in the background, so you won’t see IE 8 snooping around on the pages that you’re viewing.
However, you’ll definitely notice that it’s busy with something as page or site-flipping becomes slower.
IE 8’s Smart Screen Filter may be a handy booby trap finder, but it can be a drag especially if you know that the Websites you’re visiting are landmine-free.
If you’re sure that the pages you’re flipping on are clean and legit, then you might want to deactivate this phishing filter.
You can do this by clicking on Tools > Smart Screen Filter, then select Turn Off Smart Screen Filter.
