Tracking cookies

ive been quickscanning my computer with norton with norton360 since yesterday  everytime i am scanning even when i just scanned and scan again i get 5 tracking cookies found and resolved which means it isnt bieng resolved why is that?

Does Norton 360's capabilities eliminate the need for the browser add on's such as TACO for firefox?  How do they compare?

A great program I use for blocking tracking cookies is Spywareblaster.  It works for Chrome, Firefox, Internet Explorer plus others.  The free version is manually updated.
