Talked with tech support today approx 10:00 who was not specific as to what the square box with a down arrow was.
I asked if it was a software update like kitkat aka 4.4.2? She continued to say"it's a software update". I will not download 4.4.2, it has sabotaged my friend's system.
How do I delete the square box with the down arrow?
