NIS2009 getting stuck with files that have already been deleted

Hello,

I'm having an issue with my NIS 2009.  It found some infected files, and I deleted them by hand while the system was going through a full system scan months ago.  My install is now alerting me to the files being infected, and the files, folders, everything, no longer exist.  How do I get it to clear these?  I tried creating file path doubles for the files, yet the program doesn't see them. Any help will be greatly appreciated.
