I was looking at mediahint.com's website - though I didn't download anything. Now, it has taken over my browser. It redirects any URL I input to mediahint.com, and any link I click on via a search engine it also redirects to their page with a message saying "This is somewhat embarrassing, isn’t it? Sorry, it looks like nothing was found at this page URL. Please try using the search box or choose a help center topic." I can't escape this horrible thing! It is not listed as an add-on/plug in for me to remove, so that's not an option. I also tried to reset the browser to default settings, which also did not work.
