What is the name of this app?

I downloaded and installed it earlier this year. It supposedly hides your private messages from prying eyes. You can see the facebook logo and how many messages it has protected. I use a different mobile phone these days, and use this phone at home. Please let me know how to remove the app.

That little icon next to the Facebook icon looks like Clean Master's icon. I agree, get that off the device ASAP, that's a Cheetah Mobile app, that company is one of the shadiest on the Play Store.
