Thanks for posting the video -- you clearly don't have the exact same issue as the OP of this thread, since the icon you have is a search icon, while the OP described an icon with a "man symbol."
I agree with mustang7757 -- if you don't have some initial suspicion of which app is responsible, you may just have to uninstall apps one by one until the problem goes away.
