Welcome to Justanswer.com Jennifer, my name is ***** ***** I will do my best to assist you.
This could be a program you recently installed, or if its a globe symbol and not a sun, it could be an issue with your startup disk.
But most likely its an unwanted program. If you would prefer, I can connect to your mac from here via a screen sharing session. This will save us both some time, and allow me to fix the problem in person and on screen.
I will send the offer for that service now. If you would prefer to proceed via written word, let me know!
