Does NIS v 21.7.0.11 still remove tracking cookies?

Hi all this is a different issue than my recent post about download insight I have my NIS set to automatically remove tracking cookies when a scheduled full system scan is run (2 times a week). I have noticed that there have been no tracking cookies showing removed since a scheduled full system scan on 7/8/15. There have been at least 5 schuled full system scans that have run since then. However the full scan results do not show any tracking cookies found or removed. Out of curiosity I went to a few websites that usually have tracking cookies like Target and yahoo. Then I ran a manually quick scan. But no tracking cookies were found. I watched the scan asit was running and I did see it checking for tracking cookies, but again none were detected So has NIS changed to where it no longer detects and removes tracking cookies? Or have tracking cookies changed so that they elude detection?
