To access the update settings, click Settings/Add profile/Windows and Linux/Updates.
This tab lets you configure the automatic updates of the protection engine and the signature file.
In the case of Linux computers, you cannot configure the frequency of the automatic updates of the signature file. These will always take place every 4 hours.
In the case of OS X computers, you cannot configure the frequency of the automatic updates of the signature file. These will always take place every hour.
48 hours after a signature file version newer than the version currently installed on your computers has been released, the computers will appear as out-of-date in the Status window.
