DoubleClick Cookie

hey TF´s just a short question, nothing special.
I just ran Spybot - Search & Destroy, a programm to delete Spyware and so on.
And everytime when I visit our page I´ve got a Tracking Cookie which is called DoubleClick.
It is tracking my name MadMax... strange...
Just want to know whether it has something to do with our page or not

uhm, maybe it tracks your avatars, accounts, so you could login into another forum with same shell, just guessing.
btw. i use that Spybot, and its good, but it screwed up my system once :$
