Norton Safety Minder is very slow when browsing

After installing the safety minder on 2 machines (windows 7), browsing has become very slow.  If I temporarily disable safety minder than browsing is very fast again.  I have road runner from with Time Warner.  Is there a solution to this?  As it currently stands, I may have to remove Safety Minder.
