[HELP] Excluding files

This is something I really need to get off my chest.
Normally some files I am able to exclude by: More Details>Exclude this file.

However sometimes this occurs:
The file doesn't have the exclude option in more details and it shows me the history instead which also does not display anywhere about excluding the file. I have searched but to no avail. I read on the forums and some people said that you should go to the settings and choose a file or folder to exclude. But the thing is Norton already deleted the file. So HOW in the WORLD am I supposed to select the file I want to exclude if the file itself is already removed by Norton.

I mean seriously? It's like just so stupid. How do you select a file to exclude by Norton if it was removed by Norton no matter how you try to get the file back?!?!?!? It's like dividing by zero. Come on Norton.
