Bye Bye Flash
Your Mac may be warning you that it's time to uninstall Flash. Don't be confused about the process, though—it's easy! And yep, you should go ahead and do it since Adobe has dropped support for that product.
For that, all you need to do to begin is to visit this website. If you scroll down on that page, you'll find an uninstaller program that Adobe offers (for most of you, it'll be the link labeled "uninstall_flash_player_osx.dmg" next to where is says "Mac OS X, version 10.6 and later."
After you've downloaded that, follow the instructions on the page to complete the uninstallation. And you'll be free of the risks of malware that Flash can bring to your Mac! Whew.
Note, though, that this doesn't have anything to do with other still-supported Adobe products, such as Acrobat. This only applies to Flash itself. And if you're nerdy and curious like me, you can read more than anyone needs to know about the program on its Wiki page. C'mon, friends, embrace your inner nerd.
