Norton Security destroys files which I recover from quarantine

I use Norton Security and quite often files on my harddisk are recognized as a virus, but it's often a false-positive. The problem with this is that after recovering the file (from quarantine) it (the *.exe) seems to be broken. Fact is that it cannot be run again, Windows (10 x64) tells me that it's not a valid executable.

The file size is identical to the moment before Norton blocked/removed my file, time and date are from the moment of recovery and all the letters are lowercase in the filename. The last two things are also very annoying, but leaving a non working executable is really bad.

What can I do to prevent Norton from destroying my files?

I already set "Automatically remove risks" to "Ask" (I don't know the original phrase, I translated it from the German version). There is also the option "Remove risks when nobody uses the PC" which was set to "High security only". Now I set this to "Ignore". Will this still ask me or what does "Ignore" mean in this case? And are these two options everything I have to set?

There's a setting that you can change to not have Norton remove any file automatically, and let you decide if it should or not. For what you're talking about, I've had the same experiences.
