USB icon flickering in system tray

Hi,
The USB icon has just started flicking up for a fraction of a second in the system tray. It happens randomly but at least once every 10 secs. There is no uSB plugged in. Apparently it started happening after the kids pushed some keys on the keyboard. I have recenlty installed any new software. Driving me crazy as you see it out the corner of your eye constantly. Any ideas appreciated.

You should be able to hide that "Safely Remove" icon by right-clicking the Taskbar, choose Taskbar settings then in the section that mentions Select which icons appear on the taskbar and set that feature to Off. If wanting to remove a USB Thumb drive there's still the Eject on the drive properties in File Manager.

Seems to be fixed now. All I did was play around with the "keyboard and language" settings and rebooted and the flickering stopped. Thanks for everyones help.
