Any supposed Flash Player update you see is malware. If you see something like that, DO NOT DOWNLOAD THE SOFTWARE. Yet you may still come across websites claiming that you need to update Flash Player, and offering to allow you to download it.

UPDATE: As of January 1, 2021, Flash Player is no longer supported.
