"Certain cookies are needed for site interaction so to block them fully could / would break the site." So it seems then that the program does not recognize ad trackers as they are installed but only after they are placed and during a scan. I guess my comment is that ad trackers are not really being thwarted very much by this program if they will always keep re-appearing the same day.
I have been using the Pro version for the last 3 years and I watch the details as the program scans and finds "threats". Every day the exact same tracking cookies appear even though they were removed the day before. If the program can detect these cookies why does it not also block them from re-installing? There is not much advantage to removing a cookie if it will reappear in minutes.
