Virus signature import/export
With computers that are never or only rarely connected to the Internet, or where there are restrictions on the data volume for downloads, you can also update virus signatures via a data medium (e.g. USB stick), or run an offline update. To do so, you must export the virus signatures to the storage medium using a computer that is connected to the Internet and has the necessary permissions. You can then import them via the "Import from" function on the computer with no Internet connection. The system on this computer will then be protected by the latest virus signatures as well. Unlike regular virus updates via the Internet, here this is up to the user, who must ensure him- or herself that signature updates are run as often as possible.
