Quarantine and Backup storage
Quarantine is a special repository that stores the objects possibly infected with viruses. Potentially infected objects are objects suspected of being infected with viruses or their modifications.
A potentially infected object can be detected and quarantined by File Anti-Virus, Mail Anti-Virus, Proactive Defense or in the course of a virus scan.
Objects are quarantined in the following cases:
When you place an object in Quarantine, it is moved, not copied: the object is deleted from the disk or email, and saved in the Quarantine folder. Files in Quarantine are saved in a special format and are not dangerous.
Backup storage is designed for storing backup copies of infected objects that could not been disinfected immediately after detection.
It is possible that after the next databases update, Kaspersky Internet Security will be able to identify the threat unambiguously and neutralize it. Due to this fact, the application scans quarantined objects after each update.
