I'm sure I mentioned all this is passing 
already, but to make it shorter and to the point:

THIS annoying window appears ONLY when I visit 
Animanga and nowhere else.

I already had Panicware PopUp Stopper installed 
and activated, BUT

* this particular javascript window appears 
WITHIN the browser window displaying the 
Animanga site; they opened a window that either 
could not be closed or the window opens twice in 
a row so that the pop-up stopper can only kill 
one of them.  Nor does the special window appear 
as an extra tab on my taskbar.  It's very 
peculiar and very annoying to combat.

I already have Spybot and HijackThis installed 
and can run them, BUT

* They only help me fix the problem after it 
happens and cannot prevent it from occurring 
again (as is the case each time the window 
appears).

I already have Norton Internet Security, BUT

* I did have it on default settings.  Since 
then, I have strengthen my firewall (despite the 
almost constant prompts I have to read each time 
someone tries to contact my computer).

Also since then, I have decided to place 
Animanga on my maximum security zone of IE and 
not deal with the issue any longer.

* My only regret here is that I WILL NOT be able 
to post messages here again (with the exception 
of this case, where I switch the security back 
just for this moment) nor will I be able to 
browse the Animanga cel shop.  All in all, it's 
still a bit of a hassle.

Yann, I already posted the name of the company 
responsible for the instrusive ad, but you can
