Description

For DSM users who have installed Antivirus Essential, Security Advisor might have notified you with messages similar to “ DSM system files have been unintentionally modified. Following file(s) have been modified: /usr/syno/bin/zip. Please contact Synology for further assistance.”, please be advised that this is confirmed as a false alarm.

The /usr/syno/bin/zip was quarantined by Antivirus Essential and caused a warning in Security Advisor ("file is modified").

We have reported the false-positive file to ClamAV (the antivirus engine of Antivirus Essential), and the future virus definitions will not report such infection. If you have received a false alarm notification, please refer to the Resolution section to solve this problem.

Resolution

To fix this issue, please go to DSM > Control Panel > Update & Restore > DSM Update and install DSM 5.2-5592 Update 4 and above. If the problem remains unresolved, please visit https://www.synology.com/support/support_form.php for further assistance.
