Hi

Do you have the address handy of the webpage that keeps appearing?

Yes. gestyy.com I've searched for how to remove it, but all the directions I see are for PCs. This is on my Android cell phone and they aren't applicable.

Hi

Have you installed any other apps on your Android device?

No, not any apps. I did put a few shortcuts to some recipes on the home screen, but I deleted them when I read the directions for the PC. I downloaded Firefox after all that, but I don't really understand how to use it or if it can help.

I recomend that you clear your browsing history which should resolve this issue. This article will help with this.
