Where can I change this swipe right feature to unlock my phone?

[EnTaroJ]

I don't know how but after I enter a code to open my phone there is a swipe right to unlock my phone with ads at the bottom. Is my phone infrcted or is there a way to change it?

Most likely an app you installed. Not 'infected', just... well, crappy app, let's leave it at that. Try to see if the 'extra' lockscreen has a menu button or something that can let you either turn that off or identify the app that's showing them to uninstall. Usual culprits are battery managers/savers and file explorers.

Do you have ES File Explorer installed? If so, remove it or disable it, and the ads should stop.
