download problem?

[calluna]

hey there,
i have been trying to find the answer to this on the forums but I am not having any luck.
i seem to have accidently downloaded an sdvertisement and i can't get it to go away. now, every time i download something and try to play it all i get is this awful ad! i have tried deleting lw and reinstalling it, changing the location of my downs folder and running macscan to find spyware all to no avail!
help me please, this is driving me nuts...
mac osx tiger

if i log off or shutdown my computer will it cancel my down loads can i resume and will it keep downloading?
