How do I stop my S4 keeps shutting down on it's own every 5 minutes

[AC Question]

My phone started to download apps on it's own like Hotvideos, pornclub and now I see it downloading sexy hot wallpaper. When I ran the antivirus software on it, it tells me that their built-in malware and the phone can't erase them. Can you please help? I factory reset the phone that I've only had for 6 months by the way but now it's hard to use because it shuts down every 5 minutes. Can you please help me???

You may need to reflash the stock ROM.

I'm gonna go out on a limb and guess that you installed less than reputable apps on your device from less than reputable sources. Realistically, there's no other way you'd be encountering these problems.
