In Enterprise Console the following error code and error message are reported:
a04b0011 Threat <filename> could not be cleaned up because it is no longer in the quarantine list on this computer.
This error message is usually generated when Sophos Anti-Virus for Windows 2000+ has already deleted the infected file.
What to do
- Run a scan with Sophos Anti-Virus to ensure that the infected file has gone.
- Delete the alert from Enterprise Console.
If the report reappears after the scan, go to the affected computer and check what has happened from there. See Sophos Anti-Virus: removing viruses on the local computer for details.
