MacOS – Where Do I find the file? ~/Library/Saved Application State/com.microsoft.Word.savedState

I don't have the reputation to ask a question, but sometimes deleting "everything in Safari" isn't sufficient. Malware of this type installs files in a variety of folders. Examples include the LaunchAgents, LaunchDaemons, PrivilegedHelperTools, and Extensions folder. You need to identify the malware first, and then follow instructions on where to look, and what to delete. Resetting Safari isn't sufficient when files located outside the "scope" of Safari (for lack of a better term) and spawning processes to be used by Safari.
