Quarantine
Sometimes during disinfection, some of the data in an infected file is lost. If a disinfected file contains important information that becomes partly or completely inaccessible after disinfection, you can attempt to restore the original file from its backup copy.
A backup copy is a copy of a dangerous object, and is created in Quarantine when an object is disinfected or deleted by Kaspersky Internet Security.
Quarantine is a special storage area that contains backup copies of files that have been deleted or modified during disinfection. The main function of Quarantine is enabling the user to restore an original file at any time. Files in Quarantine are stored in a special format and are not dangerous.
Quarantine also stores files that are probably infected by viruses and other computer security threats, or objects that can't be disinfected at the time of detection.
Probably infected objects are files that are suspected of being infected with viruses and other computer security threats or their modifications.
Probably infected status may be assigned to a file in the following cases:
- The code of the object being analyzed resembles the code of a known malicious program, but is partly altered.
Kaspersky Internet Security anti-virus databases contain information about threats that have been already analyzed by Kaspersky Lab specialists. If the anti-virus databases do not yet contain any information about a modification of a threat, Kaspersky Internet Security classifies objects infected with a modification as probably infected ones and indicates the threat that most resembles this type of infection.
- The code of the detected object resembles a malicious program in terms of its structure, but Kaspersky Internet Security does not contain any records similar to it.
A probably infected file can be detected and moved to Quarantine by File Anti-Virus, as well as while running virus scan tasks.
When Kaspersky Internet Security moves a probably infected file to Quarantine, it deletes the object from the current folder and saves it in Quarantine.
You can restore backup copies of files from Quarantine or delete them.

By default, files are stored in Quarantine for 30 days. After 30 days, the files are deleted. You can change the maximum period for storing files in Quarantine or remove the limit entirely.
