An item that was detected and recorded in Quarantine Manager subsequently has the threat entry removed.
First seen in Sophos Anti-Virus for Mac OS X
All supported operating systems Mac OS X
This occurs when the detected file is stored within an encrypted sparse bundle. When the bundle is unmounted Quarantine Manager removes the threat entry when it subsequently checks it.
This is a known issue and as such no action is required.
