As you suggested I installed Avast! Ransonware Removal and ran it. After it scanned my phone I dialogue box appeared saying that I had to uninstall the software before I could continue using my phone. So I hit uninstall. When it was finished I tried using my phone and it weemed fine. The porncheckorg.com pop-up was gone and I was able to get on the internet. I just wonder however, is that correct that the software needed to be uninstalled or was that part of the porncheckorg.com virus "self defense" feature?
