I have NIS 2013 (version 20.2.0.19).
Whenever I run a full system scan, I notice that it doesn't bother to scan a number of so-called "trusted files" or "skipped files".These amount to less than 5% of the total number of files it does scan, so it wouldn't take much longer to scan these as well.
I don't know what these two categories of files actually contain, but to reduce the presumably very small risk that they might be infected, is there any way I can force NIS to scan all the files, included the "trusted" and "skipped" files?
