Databases of the Anti-Virus, Anti-Spam, and Anti-Phishing modules (hereafter also referred to as "databases") are files containing records that can be used to detect malicious code in scanned objects. These records contain information about the control sections of malicious code and algorithms used for disinfecting objects that contain such threats.
Virus analysts at Kaspersky detect hundreds of new threats daily, create records to identify them, and include them in database upgrades packages (or upgrade packages). Upgrade packages consist of one or more files containing records to identify threats that were detected since the previous upgrade package was released. In order to minimize the risk of infecting the protected mail server, we recommend that you receive database upgrade packages regularly.
As long as the license is in effect, you can receive scheduled database upgrade packages automatically, or download and install upgrade packages manually from the Kaspersky website.
About update sources
During installation, Kaspersky Secure Mail Gateway downloads the latest databases from one of Kaspersky's update servers. After installation, several update sources are available.
The main update source is Kaspersky update servers. These are special internet sites which contain updates for databases and application modules for all Kaspersky applications. If you connect to the Internet via a proxy server, you must configure proxy server connection settings.
To reduce the amount of Internet traffic, you can set up database updates from a custom update source. HTTP or FTP servers or local folders on your computer can serve as custom update sources.
Monitoring database status
Kaspersky Secure Mail Gateway periodically and automatically checks for new upgrade packages on Kaspersky's update servers. Application database statuses corresponding to the time of the last update are described in the following table.
