Thanks for posting and for the screenshot. The icon is a phone dialer app. Is it showing the same character on the app itself? May I know what application you're using on the screenshot? Thanks.

I'd get rid of the app.It's not needed and may have been installed by some ad-supported app you installed.
Also scan the system with some Anti-Virus/Anti-Malware,
Eset is good for a lot of stuff,
