Pop ups from Internet Explorer when program isn't even open?

[notachubbybutt]

I am a Firefox user and rarely use internet explorer - after I restarted my computer an hour ago I have gotten about one STOPzilla pop-up (opening on Internet explorer, which is not open) every 2 minutes. It's really annoying but I don't know what to do. Can anyone help?
