Well..THIS rarely happens...I think I fixed it!
It may or may not be relevant, but know that I installed WiseCare on an external drive because it seemed to be conflicting with a similar program on my OS drive. FYI.
IN THE WISECARE INSTALLATION folder (external drive but it may/should not matter, I renamed "WISETRAY.EXE" to "xWISETRAY.EXE". This is my standard approach to trying to stop an .exe from running before I delete it altogether. I don't think it matters what you re-name it as long as it's different.
This icon is gone and doesn't come back!
I'd like to hear if it works for anyone else?
