I have a pop up blocker as well but this thing still shows up every once and awhile when I either open or close out of my MSN buddy list. It's actually something people have had before and apparently it's malware. But I've used my Ad-Aware and it picks it up and says it's removed. But yet it comes back. x_x;
I'm afraid to think it's something that came through MSN because I use that all the time.

I really need to stop disappearing from this site.
It feels like I don't know anybody anymore.
