Files Permissions and Privileges

To scan objects of the file system and neutralize threats, Dr.Web for Linux (or rather the user under whom Dr.Web for Linux runs) requires the following permissions:


Required permissions

Listing all detected threats

Unrestricted. No special permission required.

List archive contents
(only corrupted or malicious elements)

Unrestricted. No special permission required.

Moving to quarantine

Unrestricted. A user can quarantine all infected files regardless of read or write permissions on them.

Removing a threat

User must have write permission on the deleted file.


Unrestricted. The permissions and owner of a cured file remain the same.

If deletion is applied to the file while curing, it is removed from the system regardless of the permissions that the user has on the file.

Restoring a file from quarantine

User must have permissions to read the file and to write to the restore directory.

Deleting a file from quarantine

User must have write permissions to the file that was moved to quarantine.

To temporarily elevate Dr.Web for Linux privileges in graphics mode, click the corresponding button in the Dr.Web for Linux window. To enable operation of the Dr.Web for Linux in graphics mode or of the command-line management tool with superuser privileges, you can use the su command, which allows to change the user, or the sudo command, which allows to execute a command as another user.

Note that Scanner cannot check file which size exceeds 4 Gbytes (on attempt to scan such files, the following error message displays: "File too large").
