Maybe a week ago, I started getting these two pop up banners every time I use safari. It's always the same two, and usually appears a little while after I open Safari, not sure when because they open in the background. I only notice them when I use Exposé. I tried resetting Safari, emptied the cache, and that didn't work. I have Safari set to block pop up windows. Is there any more steps I could take? Or do I need some sort of virus scan? If so, which is a good free virus scanner, and which files would I need to direct it to. (No need to scan my iTunes library.) Anyways, thanks!
