Norton Security 22.5.4.24 -- gray taskbar icon?

I'm sure this isn't an issue; but what's up with the "gray taskbar icon" in Norton Security 22.5.4.24?  I'm abso-posi-lutely sure it was a *yellow* icon before the last update.  (The answer to this may lie elsewhere on this Forum; but I couldn't find that answer.)  Does anyone know how and/or why that happened??  Or has my Norton Security gone and went HAL-9000 on me??    Thanks!
