Updating sources and update scenarios

An update source is a resource that contains updates for Kaspersky databases and application modules. Update sources can be FTP, HTTP, or HTTPS servers (such as Kaspersky update servers), as well as local or network directories mounted by the user.

The main application update sources are Kaspersky update servers. You can specify other update sources in the Update task settings. If an update cannot be performed from an update source, the Kaspersky application moves on to the next update source.

The Kaspersky application supports the following scenarios for updating databases and application modules:

• Update from Kaspersky update servers. Kaspersky update servers are located in different countries around the world, which ensures a high reliability of updates. If an update cannot be performed from one server, the application switches over to the next server. Updates are downloaded via HTTPS protocol.
• Updating from a local or network directory (SMB/NFS) mounted by a user, or from an FTP, HTTP, or HTTPS server. You can specify a custom update source in Update task settings.
