If you want to filter all files with a certain name, create the filter list using the Filter files with specific name patterns option, and then, in the file filter list, type the file name in the Filter criteria - by file name section. File name filter matching is not case-sensitive.
For example: if a virus uses a file named payload.doc, you can specify payload.doc as the file name. This ensures that any file named payload.doc is filtered, regardless of the file type.
Detecting files by name is also useful when there is an outbreak of a new virus and you know the name of the file in which the virus resides before your scan engines are updated to detect it.
