When I loaded Norton, the initial display was normal. Later, the grey x's appeared in the lower left display of the icons in my desktop display. Is this associated with Norton? If so, how can this be resolved?
Found the following - no guarantee on the fix, and not responsible for the results, but perhaps may help you:
Try to Google it as there are other results for the gray X.
The fix you referenced did not work. "Open with" did not show. Refresh did not work either. Still have the grey x in the lower left corner of certain icons.
Not trying to be a butt head, but did you read the entire thread I referenced above - much farther down the thread it mentions One Drive and updates - have you verified none of the other suggestions fixed yours?
Just trying to be helpful.
