Constant pop-up

[AC Question]

I've started getting a popup from S3.amazonaws.com on my Galaxy S5 that takes over my web browser and won't let me back out. I've researched this and can't find much information concerning this. Has anyone else out there experienced this. I've scanned with Lookout and installed Malwarebytes Anti-Malware, but have found nothing. I've cleared all the internet caches and cookies, restarted the phone, but it still seems to pop up.

Perform a factory reset. That will fix the problem. In the future be careful with what you download and the sites you visit.
