So I accidentally clicked one of those advertisements that looks like a Download button and I downloaded a bunch of junk. I went through my programs today and deleted anything suspicious and ran two complete scans with SuperAntiSpyware and it looks like all spyware is pretty much gone.
But I'm still seeing effects. Random advertisement banners are making their way into sites they shouldn't be (such as youtube, facebook, google, and wikipedia). Random words in text are underlined blue and are hyperlinked to advertisements. My homepage for IE is Babylon Search, which after doing some research, causes problems like these. I thought I had deleted Babylon from my programs (it's not listed there anymore) but it's apparently still active.
So what do I do? It's making the internet lag horribly and the advertisements are so annoying.
