How can i remove the integrated google adsense in the 1st post?

[Sworm]

Hi all,
i have need to remove from the first post, the google adsense block , or if is more simple, disabling the integrated vbulletin google adsense code and add a banner only in the footer and under the navbar......

Anybody can explain me where exactly must i put my adsense code under navbar and in the footer?

I mean,
in the vbulletin adsense options there's low - high. I have need of high (big banners) without the banner in the first post.

If i check the "low" , the banners will be small and not is that i want.

Is this the tpl to edit to remove the adsense block in the first post?
ad_showthread_firstpost_sig

If so, how can i do to edit it to remove the first adsense block?

Thanks in advance
