photo download called pwbg.jpg is on my phone

[Android Central Question]

I have a Galaxy S4 and today it downloaded a photo? pwbg.jpg It also downloaded something WRD 170? I don't know what they are or what to do with them. I found the picture pwbg.jpg in my files labeled as logo2cd2...d75a.zip and it says it cannot be opened. I don't know what to do. Phone got hot and drained, too.
Thank you for any help

The zip file can't be opened because Android phones don't come with a zip file app.

But if the files downloaded by themselves, I'd just delete them.

(If you downloaded what claimed to be a photo, but it's a strangely-named zip file like that, definitely delete it.)
