How is is possible that a personal computer can find 3-5 thousand tracking cookies the next day after I've used CCleaner?
We have discussed this in another thread. (Sorry can't link it from this phone).
It's the new, unliked by many, results display.
It reports everything found to clean as a "tracking file/cookie".
Most people would not regard these as "tracking" in the general malware sense of the word. (That would be keyloggers, location trackers, and such).
But if you want to stretch a point for advertising purposes then every cookie, logfile, etc. has 'tracked' something that you did.
It's just advertising speak
