many random files called "Icon?"
Recently, a large number of files (nearly 500 of them) from a few KB up to several megabytes have appeared all over my many external and internal drives. They all use either the icon of a very old app which hasn't worked since high sierra or the word "exec" in green on a dark gray rectangle, and the name attached to these files is simply "Icon?".
Can these be safely discarded?
