Ah, but cookies are one of the main spyware tools of companies like Doubleclick.

And just think of it this way, why would the uninstall program (you know... the program that's supposed to be *REMOVING* stuff from your hard drive) *ADD* any sort of cookie at all to your system if it weren't useful for some purpose? And I have a strong feeling that that cookie isn't there for YOUR benefit.

Just my 2 cents.
