What is 'Font.Apk'?


AC Question

( I have an Android HTC One)

I recently had a strange pop-up on my phone, so I ran a virus scan and it alerted me to 'less than positively reviewed' apps. One of which was Font.Apk. I did some looking around and was unable to find any information about this app at all, it showed up twice so I'm inclined to believe it's on my phone twice. The virus scan came back clean, but I'm still uncertain.
Along with this, I recently discovered an entire album of emojis (like the ones you'd get on an iphone, yes) but in an icon form in my photo album. I'm unsure if this was part of an odd software update, but it seemed suspicious to me, so I deleted them. Is this a potentially harmful file or core to the Android?
