sorry for bad English and I appreciate any Help.

 

deleting files from quarantine is permanently.

Anyway, Quarantined files are not a security risk.

 

If you run a scan with the "Scan without cleaning" option unticked, files will always be quarantined if a cleaning action is carried out on them. If infected files are not removed, it could be that they are locked and cannot be removed until the next computer restart.

 

thank you for your answers.
