Some users said using Mac Trash to remove Norton Security for Mac, does it work?

“After upgrading to OS X 10.8.1, I’ve decided to us Sophos instead of Norton Internet Security for Mac. Is it a simply drag to the trash from the application folder?”

The answer maybe not, dragging the Norton Security to trash is only half part of the whole procedure, you may need to delete its remained files and folders in hard drive of your iMac, too. Removing it manually will not remove all the files, and will result in half-uninstalled software that will cause other problems.
