Everytime I visit this site, Adaware complains about two spywares being left behind.
Can you do something?

I need more details, but most likely one of the ad banners set a cookie.

Yes, two cookies left behind your advertisers that Adaware does not like. It does not care about most other cookies but spots these two at every scan after leaving the site (everything cleared before coming here to be sure).
Maybe Adaware is getting paranoid :x or me 8)

That's nothing to worry about. It seems like Ad-Aware count all known cookies as spyware ;(

IE6 should block cookies of that nature. or...?
Well you can give it a go.

I wholeheartedly agree with that statement.

I filter them with MS Isa
talk about overkill.
