AutoRestore is designed to autorestore a legitimate file if it is altered/modified and also sends the altered/modified file to Quarantine. You can restore backup files on the AutoRestore page by clicking the Restore Backup Files button. Quarantine is designed to quarantine hacker files. You can View, Restore or Delete files in Quarantine. AutoRestore|Quarantine is not a Backup and Restore feature like a typical file backup plugin.
