I've searched Tom's, MS, etal, but still confused. This morning, after completing a session of Candy Crush Saga on my Windows 10 desktop, there was a black dot partially atop the Chrome desktop shortcut. It is a prefect round dot about 66 percent of the size of the Chrome shortcut. I clicked on it and then right-clicked on it to no sucess. Computer seems fine otherwise. Yeah, I know....shameful...Candy Crush. Unfortunately, I became addicted to it during a long nursing home stay Kris
O.K. Finally found something, somewhere, that said the black dot as on Chrome, means it was MY PERSONAL desktop shortcut to Chrome (and I could personalize it with my photo or something.....) So, my pix would be half off-set from the Chrome shortcut. Have no idea how that happened. And, I seldom use Chrome. Usually FF. So, deleted the shortcut and all seems well. I still have another shortcut Chrome on the desktop that has always been in the same place since...well sometime. I have, in a fit of caution, also run MalwareBytes; MSERT and Windows Defender and all are clean. Thanks for looking. kris
