I ran Comodo rating scan and find a few unknown files. Those files I believes to be safe have been posted in the white list request. However, following two unknown files cannot be found even I enable viewing of hidden files.
system.serviceprocess.ni.dll
presentationcore.ni.dll
They are indicated to be located in the "C:\windows\assembly\nativeimages_v2.0.50727_32" but even the directory “nativeimages_v2.0.50727_32” are not able to be seen.
Is it normal with this kind of invisible unknown files?
P.S.
OK. I find them in sandbox directory and will post a white list request for them.
