15 trackers always remain

HI there, some advice please...

When I run CC Cleaner 15 trackers always remain. This happens no matter how many times I run CC Cleaner in one session and no matter how many days between clean ups I leave it. When I run CC it says the 15 have been removed but when I 'start over' the 15 are back again. Any suggestions as obviously I'd prefer to be looking at 0 trackers remain.

Many thanks

Simon
