Screen Sharing (double rectangle) icon in the menu bar appears for a split second and then disappears.

The Screen Sharing (double rectangle) icon on the menu bar appears for a split

second and then it disappears. This happens roughly every minute. I can not click on it to access options or to see if there is another computer connected. Screen Sharing is turned on by choice- I use it to access my screen from my home computer from time to time. I have not installed nor am I using any third party screen sharing app to share my screen, just the Screen Sharing preference that is in MacOS. The odd behavior stops when I turn off Screen Sharing. Could malware be causing this or is there another computer watching my screen? Should I be concerned or is this just a glitch?

iMac 21.5″, macOS 10.14

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?

I think you're misunderstanding. I need it enabled on this computer as I access it from my laptop. The problem is that when I know there should be no other computer viewing this screen...the Screen Sharing icon in the menu bar appears as if another computer is viewing it. But it only shows for a split second and then disappears.
