Mistake in Uninstalling MegaBackup
After I downloaded a new version of flash from pop-up window, MegaBackup was installed on my computer. Now, it opens up every time I start my computer. I tried deleting it by clicking to show it in Finder, then moving it to Trash from Finder. However, it did not remove it. Now, it doesn't show up in Finder since I deleted that icon. Since I am clueless about uninstalling software, please give detailed directions on how to remove this from my MacBook. Thanks.
MacBook, OS 10.10.3
