Notron 360 v4 System Tray Icon Question

Hey everyone I booted up my computer this morning and noticed that the Norton 360 systray icon changed. It used to be a yellow circle with a N in the middle, but now it looks like this

Is this due to a new update or have I been infected by some kind of virus?

Thanks in advance.
