Pop- Ups

I was doing my rounds today and I notice that there's a lots of blog that have tons of pop-ups and most of the time they don't go away just keep coming. I don't know if your aware with this but please check your blog, and if for some reason you see pop-ups on my blog please let me know so I can fix it. This pop-ups is so annoying, Right now, I always make sure my anti virus is working right, so many viruses on those pop-ups.
