[Inactive] no1techblog.blogspot.com malware

hi all,

i'm running windows xp with FF 4.0.1.
every time i start FF after a short amount of time there is a popup in a black borderless window that is from "no1techblog.blogspot.com ".

i've had this for a few weeks now and have never visited blogspot.com. i think it may have come from installing an app on facebook?

is there anyway i can remove this from my system or at least stop it doing what ever it is that it's doing?

i have scanned my pc with microsoft security essentials but it has found nothing. i'm not getting any other problems at all, that i am aware of.

having searched the net for an answer i've only found 1 other person posting about having the same problem but no one had replied to his post.

thanks in advance, pete.
