Quarantine is a special local repository on a device with Kaspersky Endpoint Agent installed which is intended for storing files that are probably infected by viruses or cannot be disinfected at the time when they are detected. Quarantined files are stored in an encrypted form and therefore do not compromise your device's security.
By default, the local quarantine is located in the %ALLUSERSPROFILE%\Kaspersky Lab\Endpoint Agent\<application version>\Quarantine folder. By default, the objects restored from quarantine are stored in the %ALLUSERSPROFILE%\Kaspersky Lab\Endpoint Agent\<application version>\Restored folder.
Kaspersky Security Center generates a common list of quarantined objects on devices with Kaspersky Endpoint Agent installed. Network Agents on the devices submit information about quarantined files to the Administration Server.
Kaspersky Security Center does not copy files from quarantine to the Administration Server. All objects are stored on protected devices with Kaspersky Endpoint Agent installed. Objects are restored from the quarantine also on the protected devices.
